What he said. In addition, it hurts your hands. It really is hard to hit your attack key that often. Low HP for a melee class THAT MOVES INTO THE BOSS. Have to pay attention while you play (grinding gets old even faster than a normal character since I am not just hitting one key while my pet pots). High equip costs. Quests for nearly all your skills before 70. Those are just some that I can think of, atm.

If you have to single button press so often, wouldn't it be smart to invest in a controller? I can't see control over a character being a huge problem considering most of what you're doing is normal attack spamming. Even if you really do use a lot of keys you can learn to double map all of them and that should create plenty of room.
