you clearly never dedicated to arena hard or just bad at it, in wotlk/cata/mop arenas were THE MOST complex and fun thing, all you need to do is watch gladiators pvp movies ( hydra 7-8-9-10 for example) and comprare this playstyle to scripted raiding.
"boring" lol.
not they are kinda tbh, cause our classes were butchered to the level of tetris
It will probably start with it, but i wouldn't be surprised if we get Old gods stuff at the later half of the expansion
and no expansion will ever be pvp only since this has always been a pve focused game
