I don't really understand what you're on about. I agree it sounds like you've been thrown through a loo by idiots or trolls.

Savage blade is super terrible. Do not use it. You have your own enmity combo that is good. Haymaker can be kinda useful.

You might be using provoke wrong? It does not give you additional enmity. It simply makes you the first person on the mob's enmity list - do not use it to pull (because any action by anyone will give them lead over you at that point) or if you already have the hate on the mob. You want to pull with Tomahawk.

Overpower is better than flash, I pretty much only flash if I'm pacified or if I need to do enmity on something when I can't target it.
