Memory would be fine if you didn't have to constantly pump your main stat to avoid falling behind. As it stands, you just don't have the points to pump memory in any amount cause you'll fall behind your stat curve. Memory's a great idea, you need to limit active skills or it becomes too easy to make a character that's too good at everything and that kills a multiplayer RPG. But the stat curve's too nasty to let anyone make a solid choice at how diverse their character is.
