The best bracket is 100-109 right now because twinking doesn’t seem to exist in it.
It’s nice, wod gear is fine (as are boas) and games are relatively competitive and fun.
I don’t know about 90-99 it may be similar (though artifact weapons come in at 98).
I just prefer a more balanced game overall.
I don’t expect anything to change, mind you, as blizzard rarely goes back on their changes until the next expansion (can’t admit you made a bad decision and all).
