Just my 2 cents: PvE is the strongest point of this game, PvP is not enjoyable (at the moment). Need a better endgame.
To start I like the game overall. But it doesn't mean there are things that irk me. Since the beginning PvP was bad, I think. But recently too many DCs happening (especially annoying when game goes well!) - I can't progress with my rank because of this, since I often lose Vs lvl 10 and 11 guys (unless it's bot sending one lane, still hard though). It's just stressful for me.
PvE has been enjoyable, though, but I think we could use another heroic level for all instances, there isn't much endgame after ony, ragnaros and 160 sigils.
So, either fix PvP, add PvE content or, best of all, get both done! New minis are nice, but we need real challenge. Not just leveling new minis, it's a chore...
Anyway, wishing you all a Merry Christmas (or Happy holidays if you prefer)!
