Ok, the bottom line to this discussion is
WoW is as hard as you want to make it!
Here's a few ways to make your game harder.
- Run in less gear
- Pull more mobs at a time
- Go with no tank
- Go with nobody in a healing spec
- Run the instance with everyone at minimum gear requirement
Be imaginative, don't just play the game as you are given it. If you think it's easy, make it harder for yourself. If you don't want to make it harder, quit!
To the people who claim the game to be too easy:
The only real people with the right to complain about difficulty are people at 13/13 Heroic. If you havn't done that yet, why not? I thought you said the game was easy?
