Please Help (Tank Advice)

Just did some read up, didn't know that Marauder gains Flash as a cross-class skill. Although this means you need to put in effort to get to Lv8 Gladiator.

I'll assume it'll probably be the same as Gladiator pre-30 then.

As Organization XIll has mentioned,
1) Tomahawk > Overpower is something like an inferior version of Shield Lob > Flash. Since Flash affects a 360 degrees around the tank, but Overpower only affects a cone shaped area. If you're not using Flash, you can try to re-arrange the enemies in a cone in front of you, then Overpower them once. Use it every now and then to maintain enmity.
3) Use Heavy Swing > Skull Sunder, it gives the same effect as Gladiator's Fast Blade > Savage Blade. Try alternating your Skull Sunder hit on each mob you are thinking once in a rotation, to maintain enmity on each of them.

While its not a requirement, I think you are not doing yourself any favours if you don't cross class Gladiator and the same for Gladiator's cross classing for Marauders. I use my MAR skills on my Paladin all the time.
