Anyway, going to go over my opinions on MCSGV2.
New Lobby:
Seems great, more of a change from the huge FyreUK lobby. Might be an idea to switch every month to have variation?
More Servers:
Nothing wrong with this in the slightest, it's always great to let more people play. c:
In-Game sponsors:
Personally, I'm not a fan of the idea, but I see where you're coming from. I like the idea of sponsoring, but not potions.
I personally would think something like this.
Raw food: 100 bounty
Cooked food: 350 bounty
Iron Ingot: 1000 bounty
Diamond 2000 bounty.
More, etc.
I like the 'you have been sponsored by ____ Remember to thank them!'
Advanced Statistics:
Perfect idea, many players complain about the leaderboards, so they can aim for monthly winner, daily winner, etc.
And it gives a pro player a sweet world ranking.
Achievements:
A great idea for bored players to try and collect achievements, a perfect idea.
Game Masters:
I dunno what this really means, like a person who spreads lava throughout the map, makes wolves and mobs spawn? If so, I disagree. Probably will kill the OP person to help their friend win.
New Maps:
Perfect, nothing wrong with this at all.
Deathmatch Arenas:
Nothing wrong with this either, it'd be fun to fight in arenas.
Tournaments:
Perfect, a great challenge. Nothing wrong with this in the slightest.
Randomized Tier 3 chests. (I assume it's tier 3)
Seems fun, could be a lifesaver.
