OH resources and AP are capped via the respawn of WQ being limited. You can continue to grind AP via random heroics but that's about it. resources? pretty much only WQs.
Yes there are a few quests that are not part of the leveling process.. but MOST of them are. Although to be fair.. since you can level to 110 in like 12 hours... it's not like you've done them to death...
Actually... the OH mission table is going to be more necessary than you think.. not as bad.. but you will be sorry if you don;t level it and gear out the followers because you can get the equivalent of 2-4 WQ worth of AP form them each day.
I am sour about flight... but I made it clear... just like WoD, I will leave for a year and come back when it is enabled. Not sure why they feel that is a good thing for the game, because I can guarantee you I won;t be the only one who gets tired of spending more time traveling between WQ's than actually doing them. FLying in gam,e within 2 months will keep me i it...
It's just a fact.. I enjoy flying and the games pacing when I have it.
