"You are bad at using Provoke"

[randomrope]

I believe it would be easier if we were to think of a way of telling people how Provoke works in a simple way that can be understand by almost (some people will never learn, but heh...) anyone using it, all of that in the middle of a dungeon.

So, please, how would you explain it?

I like how you bring this topic up without giving any constructive advice. As a competent tank there are only 2 instances when you should use provoke:
1. When doing a tank swap.
2. When trying to grab something out of range of tomahawk/shield lob without wanting to move.

If you are not in either of those situations you don't have a true need to provoke. Otherwise stop tanking. I say this because if you need to have provoke explained, again, stop tanking.
