there's a key word that needs to be highlighted here, BALANCE,
ask yourself why have the following ideas not been implemented to MCSG?
-sponsors
-vip spawn items
the answer is it would throw things out of balance, everything needs to be fair in the Survival games so that it comes down to skill, not other things like money.
if there is going to be tier three chests certain things need to be met
1: the chest must be clearly displayed so everyone knows its there, (so that not only pros no where it is)
2: there must be something in place to make it INCREDIBLY difficult to get the chest. (e.g lava parkour, traps)
this is so that it take skill to get it
3: the items inside cannot be god items, it needs to be so the player has an advantage but is not a shoe in to win. this means
NO diamond chestplates or leggings, no diamond swords, NO GOD APPLES, or maybe just 1 god apple NOT A STACK,
some good ideas would be low enchanted iron armour, (at most protection 1) low enchant iron swords (fire aspect 1, knockback 2, sharpness 2) low enchant bows (power 2, punch 2, flame 1, infinity 1)
normal gold apples, 1-3 diamonds.
Great ideas would include
-horse spawn eggs and saddle (thats a really great idea) wolf spawn eggs and bones,
