So far my only attempt at soloing is with a sorcerer (you know, just had to try it since everyone else seems to be doing it).

And to echo what Illumina said, eventually it just gets ridiculous how powerful you are. I haven't even been to Spellhold yet and my chaotic evil sorcerer is 22nd level, casting Time stop - Improved alacrity - and then whatever he wants. Instant death to all who oppose me (not to mention lots of dead bystanders... oops)

I think partly it has to do with game balancing. Most encounters so early on really weren't meant to involve a 22nd level character, let alone a sorcerer. Well, it's fun for now. We'll see what the Underdark has to offer. Silver dragon scale, methinks.
