I get where you are coming from.
I liked WoW for a long time and maybe played it a bit too obsessively - and exclusively... and now I don't even bother buying or playing it until flight goes live. I am not a real fan of Pathfinder but I do accept it as a reasonable compromise (since it requires mostly what I would have done anyway) but I will pretty much never step a virtual foot in an expansion until flight is there to be had.
When 7.2 hits with flight, I'll resub. Until then, my vacation from WoW has had the pleasant side-effect allowing me to discover a few other games, so its all good for me.
