What you were supposed to do was refresh UA when the debuff had been fullt refreshed through pandemic. This made it possible to stack UA infinitely. Getting UA's ticking for 1 million each tick was easy to pull of against lower rated players.
long story short: blizzard managed to make this game utter shit again. reason being ? it is impossible to balance 35 specs. why was game so much better before ? because if you wanted to play pvp you needed to pick the pvp spec. rest is just bollocs, like having holy priest in pvp or ferals or fuckin mw monks runnin around casting, flying demon hunters and so on.
you're talking shit out of your ass.
even back in TBC where this was the case, there was still a few outlier specs that defined whether your comp could have any success or not. stop living in a bubble.
pvp feels so much more alive when nerfs and buffs happen almost on a weekly basis and people are always trying new stuff out, rather than everyone going FoTM comps and facing the same aids specs over and over and over.
it will still be a pain in the ass to gear from pvp if you have to worry about the battleground reward being a duplicate
what part of "you are GUARANTEED to get a piece of gear in EVERY bg" did you miss?
in the past it used to take much more than a couple bgs to even buy a bracer with honor, let alone chest/head/legs.
also pve has more or less the same RNG in gear. you can choose which dungeons you are doing, but you can't choose what will drop from the boss. only real place where you are guaranteed to get what you want is WQ, assuming one pops with the piece you want.
