well, you can't queue for m0 / m+, and the only reason to run heroics at all is for the call to arms bag. Not much of a loss these days.

cross realm is mostly invisible at this point, especially with so many merged servers. I'm on Hellscream, and legit can't remember what servers other than Zangarmarsh we're connected to. So meh.

I don't do LFR much personally, but with so many legendary powers tied to raid bosses, that would suck for a lot of players and alts. This would be annoying and hopefully would be designed around. Actually, now that I think about it, there's the renown thing you can buy for undiscovered powers, so maybe it's a non-problem already. I'll put this in the meh.

Loss of flying would be the big NTY from me. My time is valuable and even the almost year we're having to wait at this point is annoying. It's been said many times that no-flying just means you get on a flight point and afk to microwave a burrito, make coffee, bio, play with your cat/dog/significant other, or tab to check youtube/reddit. It's not immersive, fun, or interesting. And that's what flying lets you do, get to the stuff you want to do / get done.
