I see alot of stuff for lower lvl people, but all I see in game, me being one on Chaos, is lvl 100 dragons, pure crafters and high rating peds. There are a few lower lvl newbs in New Tris, but I'm guessing they just alts or mules or RP'rs.
It's hard to get groups going for epic mob hunts, mostly because this game is very solo friendly which I like. If you put new content in game make it for those types of people. Heck, have kill tasks of hard mobs for a special gambling tokens that we can turn in for a rare chance at fluff or an uber tech for armor or weapon. It's so bad for me I get moist when a mace of intervention drops. It's so bad I'm a B- crafter, meaning i have all my crafts to at least lvl 80. I loathe crafting btw.
Put hidden triggers for tasks or quests in Istaria like the old confectioner quests that dropped of mobs.
Put in experince potions in game that are rare to help with leveling our other schools. You know, drink pot get 1 million xp in current school. And for the love of GOD, don't attune them. Make it tedious, hard to get, heck even frustrating but please give us veterans some challenge. Cause every mob in this game is easy to kill, or insanely impossible to solo. For me anyways.
Probally should have put this in rant, but it's worth a shot.
