Try leveling up your Warrior and soloing old content with it, unsynced, and see if you change your tune in the end. It's quite fun. I do that with a friend of mine, though I haven't tried soloing as I've prompted. Duoing is enough for me. Because Warrior exists, it's possible to clear some content like the Aquaducts with a lighter party: one tank, one healer, a DPS to expedite. This works well for people who play with a couple of friends like me instead of using Party Finder to make a large party.
