I guess I'm a little apprehensive about finishing the quest series because:
A. I'm afraid I may be too powerful with all my new items (playing on expert) -- thus making the game less fun.
B. I won't have much to look forward to if I finish this questline because it's so interesting and the most relevant to my playstyle.
So, I'm asking other mages who HAVE finished the line, what are your responses to my points above? Is the game still enjoyable after finishing that series? Are there other quests/questlines equally as engaging?
