Problem is the definition of cheese is very subjective.
Yeah, pre-buffing and abusing rest was an integral part of bg1 and 2 yet some people seem to thing that anything except wandering up to the person you are going to kill unbuffed and saying hurr durr me kill u now like an 6 int moron is cheese. If this was "real" and the pc kept doing that and miraculously survived i suspect astarion or lae'zel would just murder you in your sleep for endangering their lives.
