Not much reason to be upset that they're gone. Aside from any bugs that they brought, the whole point of traits was flawed. A plugin that's supposed to implement diversity and strategy into combat doesn't work when many traits are unbalanced, literally broken, or just simply useless in just about every situation. Every PvPer used just about the same meta trait build anyways, since it's clearly the most effective overall, with maybe like 3-5 traits that get swapped in and out sometimes, and negative traits that barely effect combat, if at all. And it's still like that now, just instead of stacking power/defensive traits, it's now stacking speed2 and feedalways to clear up inventory space, since there's no reason not to. Kind of surprised speed2 didn't get removed with the combat traits; it very much is a 'combat trait' given how important movement speed is and that it is advantageous to use it over carrying potions.

I mean, it just doesn't make sense to have combat traits at all when there's clearly superior options among them and everyone just uses the same build anyways.
