That's right, they need to L2Post

.
On-topic: Yes they need to learn to accept defeat instead of coming to this place to say how something is OP/UP. If they really want to complain they should at least complain in more polite language instead of something like this.
"WTF, this thing is OP!!!!! NERF that BS."
This attitude will always start a flame war later.
Makes me feel like becoming a mod just to tell them how to actually post something useful and stop that flame war or even a writer to teach them on how to use formal English.
