So after deciding on a trio that I thought would be nice late-game (hunters with stacking Ferocious Inspiration) I got to leveling. I just hit 12, and the game is more obnoxious than it is fun. Mobs die so quickly I literally spent 70-80% of my time running to the corpse and looting it. Pets, autoshot twice, run to corpse. Its looking like ~500 kills per level if I were to just grind it out. I doubt I could instance level them as I only have three. Even if I rolled with three different classes, things would still die so quickly that I believe I'd have the same problem.

Does it get better? Am I in a dead-zone where I don't have enough clones to solo instance, but too many to make questing viable, thus making the game simply no fun to play?

Pretty discouraged at the moment.
