I absolutely agree that twinks ruined the PvP experience for leveling players.
But, instead of separating twinks into broken brackets that will never house a BG, how about Blizzard just reintroduces templates or scaling below level 120? That will decrease queue times while giving everyone a level playing field.
I did not turn off my xp to crush undergeared players. I simply do not care for rated PvP or PvE, which are the primary ways to gear at 120. I PvPd at max level from MOP to Legion, because of the existence of vendors and PvP gear (or templates,) but I hate RBGs, M+, Raids, Emissaries, etc. I just want to do unrated BGs and skirms, and that’s not a viable way to gear in BFA. You need to push rating and/or progress in PvE.
So I turned off xp at 119 to get the same type of gameplay as 120 (all talents/spells available) without the constant gear grind. I will not sub to this game for max level Pvp. I do not spend much time playing this game, and when I do play, I want to actually enjoy what I am doing.
