[My opinion - I think the balance is right!]

I did quest "Noise in the woods" and you know it gave me 70 k xp. That's a LOT. 
I'd say screw these new quests and do only old grind quests but most of these do not exist anymore.
Same goes for starter quests like "What women want" in EV. 
Almost all new... that's supposed to be classic?

The only way to feel old-style gameplay is to not take those new quests actually.

I don't think so.
I really liked oldschool quests which gave some shitty adena and really no xp... well I always liked first 20 levels the most... then yesterday I did one "new" quest and got two freakin lvls for nothing... I loved to get that 0.35 % xp per mob and the fact that this would bring me slow but steady adena... now on lvl 13 I have no money because new quests catapulted me from lvl 6 to 12 in seconds.
