I don't think it should change either way. There seem to be plenty of people having trouble doing HM Titan, and very few who are doing the Bahamut raid. As it should be, not everything is possible for the average player, some stuff is just slightly out of reach. I'm quite happy with the difficultly level. It's a nice change from GW2 where there was no challenging stuff outside of pvp.

BTW, I really can't wait for the pvp. That i where the real challenge usually is, at least for me.
