Bongo

A few days ago, running the latest steam version of the game, I created a Monk where I know for sure that I created it with 18 might. At some point, seems to be as far back as I have saves (used quicksave/autosave mostly) the character's might is decreased to 14. I've ried taking all armor off and zoning but I can't seem to figure it out. All other stats seem to be where I created them. Doesn't make sense. Any suggestions on how to solve this?

I've finished the game twice with full parties and want to try solo. I'll probably only play on Normal as I'm not a pro at the game and was thinking anything BUT a Fighter or Barb. What's a good class and build for that class for solo run through success?
