I like having the mode in, specially with RPG's, which typically have rather poor mechanics for combat, I'd rather just see what the narrative, story and/or setting have to offer rather than spending ages swearing because I can't master the "dodgy console port challenge"(TM) of "Hold down both mouse buttons and drag in a direction which is perceived as a Very rough guidance as to what I want it to do while spamming Alt gr for no good reason"
If the game's mechanics are fun, or I enjoyed the story or other earlier reasons, I'll just play it again on a harder difficulty - not rocket science.
