XP is not the problem.
Mobs are too easy, they don't agro much, nothing special when it comes to attacks, 2-3 hits and they down.
And the mobs need to WALK more. I found so many that don't move at all, I can rest and pick my attacks, easy pulls etc. Way too easy, nothing to fear.
I sure feel old when playing, sometimes I ask myself "was this made for +3 years old Lego Star Wars fans?"...
