Need some pointers.

Never ever spam overpower .

Well I don't know about that.. overpower is usually worth the starvation(3 or more targets). Especially if you can Flash.

When you hit 60 you might opt out of flash for awareness/second wind, but that's up to your playstyle. Warrior starts getting fun at 50 and ashmazing at 60.

A typical pull for me is
I'm seen first, tomahawk largest threat as its father away, move to the right of the mobs, overpower, face the mobs away from group, overpower. Flash definitely helps in messy or aggro interfered pulls.
