Fun is not the same for everyone. To the OP, fun is facestomping people and winning. To the other guy, the level 12? Roleplaying like a BAUSS.

Here's what we did: Use the experimental device to destroy 2/4 turrets before engaging boss. Then attack the boss with tank. You should cleanse the thermal detonator as it deals 4k damage over time and can kill anyone in your group. This is a random attack. At 75% hp he will summon droids. The tank can tank all of half of them. Just DPS them down and heal as normal. After droids are down, dps him as normal. At 50% he will summon droids again. Tank them again and kill them. Boss will enrage after droids are down, always after the 50% mark. Dps the tank down to 25%. Make sure you keep the tank healed during DPS phase, just use some cooldowns as the DPS is around 2000 damage a hit but no one-shotting. Remember to cleanse (its helpful to have 2 healers for this fight or an off healer with cleanse/backup healing). At 25% more droids come. You can tank the droids (always to pull them off of healers/dps) but more importantly you can either kill the boss or kill the droids. We DPS'd the boss down at this point.
