As above i have played every expansion and this game since release and to be honest the best expansion was tbc well tbh wotlk was alright,and now this game or world of warcrap has gone downhill since then.
Mists of pandaria sucked i did not pvp much *as i know greg street cannot do his job properly* but i mainly done pve but there are too many dailies to help you collect valor so you can gear your character up in order to progress faster took too long as i have minimum time these days ruined it and i also loved gearing up alts.BUT IMO i think flying mounts ruined everything in this game its supposed to be warcraft in the world travelling aboutand encountering an alliance or horde then you cant really much get away but with flying mounts you can.
Overall the new talent system is a pile of crap its no good ghostcrawler wants to cater to kids and to make these dailies mandatory to get rep to collect patterns for your profession and valor for gear is a bunch of balls it will not keep players it will infact lose players and the last rant i have is class balancing after 8+ years havent the developers and ghostcrawler learned how to balance classes yet and not listening to whining kids,i have noticed on the official forums they give into whining kids and buff the class or nerf the class depending on the type of rant.
At the end of the day my subscription ran out last month i do not feel the urge to play this shit game anymore.
