Trash doesnt spawn after hard mode is enabled.
we do 1 tank 2 heal...7 dps. (always done it this way to get 210 sec achievements)
samething - gravity bombs leave a voidzone after they go off.so make sure u move outa the grp
light bombs spawn a life spark..which can be kited..they follow normal aggro table..but u should move outa the raid before the life bomb goes off anyway so it spawns outa the raid and can be dpsed quick.
We do the fight the normal way - I tank the 2 big bots that spawn during the first exposure....after his heart is destroyed we kill the 2 bots..and let all the repair bots hit him (since his HP resets after "heartbroken" anyway)..we dps the bombots though.
then we start teh fight again..only thing to watch is tank dmg and gravity bombs+light bombs..move outa the grp so u dont get voidzones/sparks in the raid.
its a very easy fight...forgot u take periodic dmg in hard mode..forgot exact number but its less than 800(perhaps 800)
