Matter of fact, where I play (EU horde), queue times have gone down from 10min to instant/couple of minutes ever since the release of cataclysm. They in fact DID come up with a solution: merging battlegroups. Many of the reasons of long queue times are player related though: not paying attention to when it pops (so they had to extend a player his slot), players who dc due to crappy connections, ... etc.
[/QUOTE]Frost mages and rogues are insanely OP at the moment (in single toon & boxing) and there has been no attempt to even out the classes (ele shams and thunderstorm being resisted 90% of the time anyone.....?). [/QUOTE]
Yes in cataclysm there have been really OP specs, and often they were toned down a bit later (warriors & ferals at the start, frost dk's with 4.2 ...). Matter of fact frost mages without any pve pieces are actually fine. The OP thing is the pve gear and the human racial. The pve gear will most likely be addressed in MoP (check new stats system). They might have it wrong, yet they do attempt to fix it.
The only thing you can't do cross realm is do arena, due to the existence of battlegroups. Anything else can be done cross realm. I wouldn't really call that a small change. It's a massive comfort of life thing for players that you can team up with other realms, both for pve and pvp.
Twin Peaks and gilneas were very well received by pretty much everyone who run bg's. And in my book they are awesome maps. I don't know how many new BG's you expect each patch, but every expansion 1-2 new bg's seems pretty fine with me.
I'm sorry but many of the things you wrote are simply not true. Which doesn't mean I agree with blizzard all the time, matter of fact they screw up things quite often.
