This is a terrible idea.

MMORPGs are social games by nature. And in the end, they must require the player to interact with other players to continue to advance. Raiding and getting pvp points are examples of this.

Raiding in Warcraft, for example, is capped to 30 some odd players the last time I checked. Do you realize how much of a pain in the ass it'll be to tell those 30 some odd raiding members that they will not be able to play earlier that day (especially a problem for raid leaders as they invariably must do some prep work in the game beforehand for the raid) or that if the raid goes on long enough, she might forceably be logged out in the middle of it?

What's worse, what if the time limit hits just as the raid has cleared to the boss or in the middle of the fight?

Players would see this as nothing more than cockblocking by the developers to limit content consumption. And in the end, more and more players would feel cheated.
