That doesn't bother me. What made me gravitate to Diablo was how they did the story. The plot of evil vs good and angels vs demons in a eternal conflict is cliche and overdone. But I liked how Blizzard handled it and I've been glued to it for a while. Mephisto is my favorite character overall and damn they're having an expansion coming soon, that revolves around him, so my temptation will be even greater.

So no it doesn't bother me that it's "too easy" or "almost impossible to die", because my idea of fun is not to have a very frustrating experience.
