Literally if you added like 5 maps but they were all clones of Nagrand in different shapes I'm pretty sure the PvP community would love you.
Things like a Vashj'ir Fishbowl or a wow gold Deepholme Crystal formation or a Uldum.. desert thing.
Things like Ring of Valor are just bad design; did you know as of this moment you can blink through the pillar and fall into it, and portal does the same thing if the pillar is moving? It's still really buggy. Not only that but the Pillars rotating, while cool in concept, just doesn't work because it penalizes positioning. The pillar you're behind in a great position could fall and now you're in the middle of nowhere with no line of sight where spell or melee cleaves can just rip into you.
I think there's a disconnect between the PvP community and the developers. While the tweaks to battleground maps are great and new maps are cool and all, we expect and hope for just as much balance as the PvE community.
Things like restoration shamans being the best healer.. and then giving them another cooldown in SLT. Warriors two shotting everything for months. Just as the MMR bug was rising in popularity.. the season was extended another week. Things like this just annoy the hell out of PvPers.
