No, sadly not... we had him change to Entropius 4 times now.
The co-ordination on the muru encounter is incredibly hard. Its Vashj + Kael combined on steroids.
We had Entropius to 89 % last night... but the hard part is still the transition from phase 1 to 2. The timers are so incredibly tight, and there is just no room for any error. When phase 2 starts all hell breaks loose, its lightning blasts all over the room, there is adds running around, there is debuffs stacking on you, there is Entropius walking around the room killing everyone in range, there is black circle's on the floor below your feet killing you in a sec or two, black missles following ppl blowing them up... Baah its just chaos, absolute chaos.
And its true... you need more dps here than required on brutallis...
*edit* Most guilds / sites claim if you can take muru down... Kil Jaedon shouldnt be that bad. Lets hope so... Muru is just stupidly hard.. even after the nerf.
