I've been seeing people complain about "uber" characters, For example, people don't like "Uberminster" (Elminster) and are even starting to turn on Drizzt. I like the struggle of playing low-level characters, trying just to survive. I do, however, also enjoy occasionally having a character who can kick butt. When I played pnp Vampire, for example, it was nice to be somewhat powerful in order to play the cool, tough vampire.
So my question is: do you prefer playing weaker characters who have to struggle, or more powerful characters who can smash their enemies? At what point do you become "too powerful"? Do you think that a character with a good history and good roleplaying possibilities should be shelved just because he's become very strong? If you play a character like Raistlin who seeks out power, should you be forced to retire him when he achieves his goal?
Thoughts?
