Is using stealth an exploit?

[Brista]

The ability to slip the "holy trinity" to the end of an instance is what I belive is against "the spirit of the game", not simply that a class can stealth

I am absolutely convinced that you and Kandrathe are simply wrong about "the spirit of the game"

The spirit of the game is that different people should be able to enjoy it in different ways. That's what attracts and sustains a large player base, what makes the game so appealing to the very diverse audiences in different countries

Most people find some way of getting satisfaction from this game that many other people would not particularly enjoy. Whether it's zerging, farming, pvp, or tactically perfect instancing people enjoy the game in different ways, as I'm sure the designers intended

Think back to D2. D2 is on the face of it a very similar game to WoW, but people never approached tactical challenges with a tank, healer, crowd control set-up: the holy trinity of everquest. Where do you get the idea that WoW has strict design intentions about group composition and tactics? It seems utterly contrary to good game design and broad appeal
