Max damage increase stacks are way too strong. Being able to get 24% damage increase is insane and makes it a must pick
Can get 12 stacks of max damage increase, and they give 2% each, so 24% damage increase. Might be possible to get even higher than that, but it's just the highest I've seen. Basically means if one person has it and the other person doesn't, the max damage stacks person is gonna win unless they seriously screw up.
There shouldn't be "absolutely take this" enchantments, takes away all the choice.
