When i first started i made a fighter. But then i switched to rogue.
There are pros/cons of each char. You have to decide which weapon type you want to you, most importantly, which will tell you what char to use. Weapon dmg is based on ratio's, so You have to choose the char that suits the weapon. Personally after seeing mages in action, I would recommend that, but I've never made one yet, might be expensive.
So before you spend your fg on items, decide what weapon type you want to use, or charm type, then pick the char with the best starting stats for that weapon.
For example, fighters are probably best with axes, bc the str/dex ratio is 50/50. half str half dex. Look up a guide, theyre around here somewhere..
