Unlikely, given LFD and LFR's popularity.2. I'd like to see Valor point farming from various activities return to being the end game for non-raiders.
I'm down with this idea.3. I think they should add a solo queue to rated battlegrounds and get rid of random battlegrounds. The problem with random BGs is that they are too random. It's like trying to play a sport with no sport leagues. There is nothing to stop arena players with decked out gear from stomping casual players in random BGs, and no matter how well you play, you can still get stuck on teams full of AFKers, bots, or honor kill farmers. At the minimum, they should add a hidden rating to random BGs if for nothing else than to allow the game to form more even PUG teams. It might encourage players to work together more if doing well means they get on better teams in the future (and potentially quarantines AFKers and bots away from players).
More art is always good. Lesdoet.4. I think they should make multiple aesthetic maps for each existing BG. Nothing makes a PvP game feel older than playing the same map you have seen for the past 8 years. How about a little variety in the scenery?
They're working on this, as of dev panels at Blizzcon. Another one they pre-empted you on!5. The transmog system in WoW is terrible. If they had made a bit array that remembered every piece of gear that character had ever equipped, that would still take less space on the servers than the system that is currently implemented...and it wouldn't fill up a player's bag space. If they wanted to optimize it more, they could just make it so that all green gear from prior expansions was always available, etc.
That'd be nice.6. A unify gear colors option - it would be nice if you could toggle a setting that would recolor all the gear you are wearing to be the same color scheme as your chest piece. It probably won't happen because of the way Blizzard optimizes their textures, but I can dream.
I think they do already...7. I think they should allow horde vs. horde and alliance vs. alliance battlegrounds for the sake of queue times.
Again, more art is always good!8. I wish Blizzard would add some civilized shaman transmog sets. After a while, I get tired for wearing lava and neon feathers, etc. Is having classic fantasy armor to WoW so terrible?
