1) Questing is not a content ANYMORE. It used to be "a part of the game", get to know the lore, escalate threats where we finished em off in dungeons (later in raids). It used to be hard and took long time (I agree), but nowadays questing is just "something in my way til I can actually play WOW". With group quests gone, it's not a social content either, it's very competitive (even against your own faction). Only reason you get invitation from someone is because you have a tag on something the other needs and doesn't wanna wait for it to respawn.
2) CRZ : This idea would be great IF the group quests existed. Nowadays, CRZ is just a punishment. Either another faction member were doing the same quest as you or alliance high level just ganks you. CRZ in quest zones are just lame
All in all, Blizzard forgot the days where questing and leveling actually were a content on itself. And that's why it's kind of ruined.
Edit: Not bias poll at all *lol*
