As you get higher in level, the corresponding mobs get more difficult. The answer to this is to learn to use your interrupts on whatever long cast ability the mob has. It makes the combat easy again.
You're not kidding. I finally beat Valis on the asteroid and now I'm on Tatooine, and I feel that's where the difficulty ramps up. But I love what they've done with Tatooine. For a desert planet, it's beautiful, and I've always liked the architecture. Has anyone pinpointed where Luke's house would be in Anchorhead?
It feels that authentic.
