So much for elitism. For a mainstream MMORPG.
Classic dungeons are not really exclusive to anyone, as they are easy. As like everything in classic, the real brick wall is time effort, and not skill effort. The time effort to find a tank in the LFG chat in a major city. The time effort to travel to the dungeon. 1 hour plus 20 minutes just spamming a chat channel and doing the trip to the dungeon.
Thats not immersive, that is time spent for nothing.
