That's the part that seems to confuse people. Leveling is content. It's something to do. It's fun, it's how you get items to sell or craft with. The drop rates right now are insanely to high as well. I spend an hour hack and slash on puks to get from 15-18 and i have a hundred puk wings and hundreds of crystals? Where's signet, first off. It's the little things that SE keeps forgetting and it's really annoying.
