I'd feel more like queuing for lower level content if I could use all of my spells/skills. There hasn't been ANYTHING under level 50 that I haven't said "Wow, I wish I could use X, Y, or Z..." I don't care if I have to jump through hoops to get "the same DPS" as a sprout (which auto-attacks seem to be able to do because of iLevel scaling...) and if I am doing it, it's already irrelevant difficulty because most of the stuff I can do alone or with one other person...
Not having AoE in early stuff SUCKS. It makes it really hard to go near the Leveling Roulette.
Someone mentioned earlier in the thread that newer players not having the stuff you're using would turn them off and that is the most bonkers thing I've read, haha.
Seeing what you're going to be getting in the future when you're leveled is the reason I've gotten most of the classes to level 70 that I have! I can't even fathom someone seeing a higher level player use a spell/skill and thinking "Well I'm not gonna play since I'll eventually get that..."
