MM6 TCC the way I play it. I do not employ offensive magic EVER. Don't even allow my characters to learn the offensive spells. I only use magic for Healing, Buffs, and Travel.Furthermore I Always play in the "Iron Man" mode, i.e. Dead Party=Game Over and no aggresive save/reloading allowed. The only save allowed is if I quit the game for some reason and wand to restart later then that save (if used) is deleted manually. Saved game or party editing is a no-no for me also.
I play all the MM RPG's that way and it is alot of fun (for me).
I also NEVER use Sorcerers or Liches. I do use Druid's in MM6 sometimes but only if I am using only one spellcaster. For me ofensive magic takes the fun out of the game as it is generally overpowered at the higher levels.
Just my 2 cents worth.
