I have played the melee type of character for a while now. I'm wanting to try a caster class. What is making my decision hard, is that I'm mostly a solo player. What would be the best class or multiclass combo for a solo caster? I don't want to be a buff casting fighter. Going for primary attack as casting and maybe a splash of melee; since it seems like melee is necessary sometimes in this game.
I was thinking:
Wizard
or
Sorcerer/Paladin
or
Wizard/Fighter
Would greatly appreciate any opinions.
