Cooldown combos?

[RopeDrink]

As a Warrior I weave REP & INT inbetween standard combo presses on problematic mobs. Low Blow I hold for stunning during big pulls or during aggro-pickup if I'm sprinting (eg. sprint, tomahawk mob-1 (GCD), Low Blow mob-2 whilst running past it as it's oGCD, spin-turn tomahawk the same mob, run into the next bunch, self-heal for instant aggro on all of them, round them up for an Overpower and then work on self-buffing before inevitable IR-UNCH-Cyclone bonanza. Chances are LB will be cooled during massive pulls so you can throw it into any surviving problematic mobs to halt any AoE's. Failing that, if you notice something has dropped aggro, you don't always have to provoke or ultimatum when you can low-blow it while giving it an aggro combo.

Another example being the Burn - those giant worms with the massive AoE's. It's handy to Low Blow one and silence another just to give any melee in the group some extra uptime, otherwise same principle.

As for Holmgang, that is one CD I'll save for OhNoes moments only. If the Healer is struggling and you just know you have a chance of eating dirt despite defensives being popped for whatever reason, becoming temp unkillable can save the day. Any other application of it will typically give healers a heart-attack without communication (and let's face it, 90% of roulette's involve no chat).

@OP, the best advice I can give you is to not look solely at one role (in this case tanking) and instead to make a habit of judging the trinity (ie. your group). A tank will look like the bee's knees if the healing is on-point (more so if they are contributing damage) and the DPS are wrecking mobs. Dead mobs don't do any damage after all, so with respectable DPS and a damage-capable healer, particularly WHM's due to constant stuns, it'll seem like tanks are unkillable monsters, whereas the reality is it's a combination of the whole team. As far as the tank is concerned, provided they know how to rack enmity, when to lob out their defensives and when it's safe to throw out damage, everything else is on your fellow party.
