Im sorry i mean on the boss or near the boss.

I never said that sustain is the worst idea, but there right now there is no sustain and my pet is still able to survive without dps lose.

I just dont understand why so many guys want sustain.. i mean there are way worser things... titan is not able to get aggro sometimes, if you summon Bahamut, Titan is losing all the aggro.
The pet control is bullshit sometimes, is not reacting everytime, if you did one mistake or the healer is not healing you, you are losing all your Aetherflow stacks your pet and your dps is going down around 1k~.

Sustain will not change any of this problems, it is just making things better for guys that dont wanna control there pet, but thats it.

If the pet would be more responsive then it would be easier to control the pet, thats it.
