Oh I wholeheartedly agree, I just think the warrior community in general has flip flopped between arms and fury more than other classes flip between their specs. Just feels natural to go back and forth for me, especially in warlords when fury and arms were almost equal in PvP and you went to arms for cleave and fury for ST in Highmaul. Good times. Whereas you know, a feral/balance druid kinda picks their spec like it's their entire class. Same with frost/unholy DKs; I feel like you completely commit to one or the other.
But yeah, AP is also the biggest factor in limiting my alt enjoyment. Sure, there's a catch up mechanic for artifact knowledge but it just feels bad that your alt is sitting there at low AP gains for 5-6 weeks before you feel like it's actually worth the time investment to go out and get artifact power.
