I saw a couple of suggestions in this thread that I don't agree with:
No horses please. From my understanding, horses are meant for transportation and not for combat. I haven't tried them in snapshots yet so it's not for me to say but from my understanding they're horrible to use in pvp. Also you need saddles to ride them, you need to tame them, they need armour otherwise they'll die, etc etc. Also, in the rare event that they
are useful in pvp, they'll probably be quite OP. Additionally there's a lot of maps where horses are just not feasible, such as Breeze Island or Solar Frost. EDIT As cool as horses sound, I don't think they'll work with SG /EDIT
No Opples please. Opples being enchanted golden apples. I saw someone suggest this and this is a horrible idea. They give you regen III (or IV?) for 30 seconds during which only void damage can kill you. You'll survive everything else.
No Fire Aspect enchants. Fire from flint and steel is already really overkill, and fire from Fire Aspect lasts even longer afaik. Even then, using flint and steel is somewhat challenging whereas with a Fire Aspect sword it's just a game of tag where you light your opponent and take some distance while the fire does the damage.
As for my own suggestions:
XP Bottles. Maybe 4 or 5 or so. Also, could you modify the enchanting system (I know this is possible) such that it only gives you sharpness on swords, power on bows and protection on armour? I remember getting Smite I multiple times after fishing for a while, is not nice. Or at least prevent people from getting Fire Aspect or Flame as this is really OP, as I outlined earlier.
Speaking of spawn eggs. Someone else here suggested wolf eggs. I remember that there used to be bones in chests, why where these removed? They could be used to dye armour so it looked like Iron, and on maps like SG1 and Hungry Hills there were wolves that you could tame. I think readding bones and then adding wolf spawn eggs (in batches of 3? Wolves are not that strong) to Tier 3's would be cool. Or maybe let wolves randomly spawn on the map.
Ender pearls. Just 1 though. Also, please don't remove the damage they do. I've never had one ingame so I don't know if you did, but I know there's an option for it. They should do damage.
As for balance, enderpearls can be considered somewhat overpowered because you can get out of a fight quickly, but since people will have only one (or rarely 2) it's acceptable in my opinion. And they're already a sponsor item, so you guys already took care of things like pearling into places you're not supposed to be? Actually, speaking of, what if I pearl on top of the corn on SG4? No one could reach me there while I could stand more "in the middle" than other people since the crafting table below is in the way.
Diamonds. Some people suggested diamond boots or helmets. I think this is not a bad idea but I'd rather see something like batches of 2-4 diamonds in tier 3 chests, still giving you the freedom to craft whatever you want.
Potions. Some potions are really overkill compared to others. Here's a simple list of which potions I think should be added and which shouldn't (also, this is assuming 'default' versions of each, so not tier II, and not extended) (Also some of the values are as I remember them, I may be wrong):
- Regeneration Potion. Incredibly overkill, will heal up to 20 hearts in total while it's active for half a minute. RANT This potion ruined high-tier pvp /RANT Do not, I repeat, do NOT add.
- Swiftness. Gives you a 20% speed boost. I think this one is acceptable, but it would be great if the time it lasted could be reduced. I know you can make custom potions, how about a Speed I lasting a minute instead of three?
- Fire Resistance. Negates fire damage. Since it only removes your opponent's ability to use flint and steel, I don't think it's all that OP. Would add. (though the same as swiftness applies here: a custom potion lasting just one minute would be cool too)
- Instant Health. I think if you used drinkables instead of splash versions these potions would not be that bad. Drinkable Health I's heals 3 hearts but takes 2 seconds or so to drink. These would be nice backups for longer fights or team fights, but it's not like you can turn around quickly splash yourself six hearts with a Health II and continue fighting. Would add drinkable I's.
- Strength. Even strength I adds 1.5 hearts with each hit you deal, and Strength II even adds 3 hearts. The only case in which I would be okay with these being added, is if it's a custom potion that only lasts 15 seconds or something. Like a short burst - use it well.
- Night Vision. Useless, is GammaBright still allowed? I remember it being allowed because you could just go into your minecraft jar and crank up the brightness yourself. If it's not allowed anymore, it may be something for Tier 2's. Ultimately they're not a combat potion though.
- Invisibility. Nope. Unless you have a Fire Aspect sword or a Flame bow, invisibility is overkill.
- Poison. (splash version obviously) Don't add. I'm pretty sure that even Splash I, not extended, does enough damage to bring you down to half a heart overtime. Unless of course, again, you can make a version that only lasts 8 seconds or so.
- Weakness. Takes 1.5 hearts off the damage you'd deal for a minute, would not add, considering we're playing without Sharpness V and that kinda stuff.
- Slowness. If I recall correctly, this decreases your speed with 15% so it doesn't even completely cancel out swiftness. Lot's of people see this as a bad potion, but it's actually the best debuff potion (besides anti-regen's). Would definitely add this, especially since it only lasts a minute.
- Harming. Does 3 hearts of damage, which seems a bit overkill, but these things are really hard to aim with, especially when there's lag. If you use it wrong, there's a good chance you'll even hit yourself. Consider adding them.
I have quite a bit of experience with potion-based pvp, if you'd like to know some more about the (dis)advantages of certain potions, please ask away.
By the way, about those custom potions, maybe you could consider making the following kind of potions: one that gives you strength I and slowness I for a minute, or weakness I and speed I for a minute, or regen I and slowness II for 10 seconds, etc etc
EDIT: Also, as an extra idea: how about crafting benches? I posted this idea before but never really got a reply from developers on it. What if you right click the crafting table somewhere, it opens crafting bench screen that you can use only once, and the table isn't placed?
