just give up on wow pvp or play it as a fun distraction with some stupid non fotm comp and have fun. theres like 10% off the playerbase left in pvp and every season after season 8 sucked dick. with a few exceptions like the end of mop but it didnt matter anymore at that point because nooone is playing anymore. there was more people playing 5v5 in tbc and wotlk then there are people doing 3s now ... also everyone that was ever good at this game has long quit and all that is left are the same 20 people going to blizzcon every year because its free money for them and some tryhards who can't move on to other shit in life . i got bored after 6 seasons, i can't believe how people can find the dedication to do the same thing over and over again for almost 8 years now. arena is a minigame that got out of hand and was never meant to be the main pvp attraction. wow was also never made with arena in mind so there will never be real balance.
if it wasn't for the blizzcon publicity wow pvp would have probably just been battlegrounds and some skirmishes. you guys are lucky that they even put effort in trying to balance this game instead of creating content for the other 99% of the playerbase.
