I make my own class The skills I use the most go into Major/Minor for quick n' painless leveling. If you're going with a warrior type class you want something like Long Blade, Block, Heavy Armor... typical warrior stuff.

Acrobatics is nice as a minor because you can level it from jumping up and down a bunch of stairs for a few minutes. Likewise with Athletics because you just need to run/swim to increase it.

I am also fond of Speechcraft/Mercantile because you do a lot of trading anyway.
