just played an hour of 1.9 PEEEVEEEPEEE
it was fun at first but then it just mainly revolved around who has better aim during the awkward circle strafing and jumping around each other in a 1v1 with nobody hitting each other in order to charge up.
it was also hard to sprint, knockback seemed different, and getting into group battles is worst than group battles in 1.8 (hits from every direction, weird knockback, potion effects, charged hits, etc.) and many more awkward moments.
if you think you are going to git gud becuz 1.9 pvp requires a lot more skill, then RIP.
1.9 pvp is shit
git gud in pvp or you're just going to become somebody who has a big mouth behind a screen
