Completely. We are now playing 2 pure wizards. We are 5lvl now and we do not have any dificulties in combat so far (tactical mode). Summoned spiders/zombies ect. are far more useful now so they don't die from 2 hits like they did in original game. We use companions (thief and archer), but I think it's completley possible to tank with pets now. It's hard to play 'cause mistakes can and will lead to death, but if executed right 2 mages have exellent control over the batllefield so far, even with few spells aviable.
