Low level Warrior/Mace tech to make things less painful

Step 1) Socket Overpower support (50% stun build up) into Rolling Slam
Step 2) Socket Impact Shockwave and one of following supports into Boneshatter: either Brutality, Heavy Swing, or Execute
Step 3) Click once to cast Rolling Slam
Step 4) As soon as the first hit of Rolling Slam connects with the enemy, immediately click to move
Step 5) Rolling Slam should have put at least one mob into Primed for Stun state, hit that one with Boneshatter for massive aoe dmg.

If Rolling Slam doesn't hit hard enough to Prime for Stun on the first hit, add in a damage support gem. If it hits too hard and stuns everything, remove the damage support you have in it. This tech has made leveling Warrior way easier and smoother for me.
