Nop.
I went and tested out the quest system after the patches.
What I found:
-Quests are pretty much kill 1241451345 mobs and get back to the npc for a reward.
-Rewards suck
-Armor or weapon pieces aren't what the character at those levels need or would like to have.
-Exp is ok-ish but Lower Gratt and Ash'Keena dungeons gives you like 3-5 times more exp with the amount of time you spent doing said quest).
-Did I mentioned that doing said quest will make you walk a lot just to blow 3-4 hrs of game time to get like ~10% exp?
Recommendation:
-If youre a new player go and grind at Lower or Ash'keena dungeons you'll be bored to insanity but youll make way more progress than questing.
-If you're an old player go to those old school spots, they are mostly empty and you can solo them with ez thx to the damage boost all classes got.
