Do NOT make the same mistake as FFXI.

Care to share which of the Ogre's AOEs can be stopped by which skills?

You keep saying to think more while fighting, and yet you don't seem to be willing to suggest anything.

Honestly, the only skills I know of that that can interrupt enemy skills are Barbaric Yawp and Shield Bash. Barbaric Yawp is absolutely worthless, an interruption skill on a 2 minute cool down, and Shield Bash is on Gladiator. Besides, the last time I fought that Ogre I could have sworn he had 3+ AoE's, each with a 10 second cooldown or less.

Right, they could easily balance that by giving his abilities a certain timer for use, and an indication they are coming or a cast time just long enough to stun. IE like glowing for 2-4 seconds.

Anyways stunning doesn't have to be the only way to stop it, but it's one way that lets melees participate.
Right now the strategy is to stand out of range and shoot it down.

Well the Ogre only has a couple attacks:
A single-target punch and knockback (Bone Breaker).
A 180 degree frontal Double Slam.
A 180 degree backwards Elbow Drop.
A 360 degree fire elemental Inferno Drop.
A very large AOE stun.
His normal autoattack, which is single-target physical damage.
His normal ranged attack, which is AOE fire damage.

All of these can be used generally within a couple seconds of the last one.

So I doubt the 2-minute cooldown ability would help, even with perfect coordination from all 8 people to use it.
