Saying it's all just a script is well and good, actually executing it like such is a whole different matter and you know it.
Actually not that much.

I did kill O3S with a RDM the week I leveled it up to 70. I played it safe as hell and certainly lost a lot of DPS but mission clear is mission clear no matter what. I already knew the whole fight, it was just a matter of applying the knew boutton press to it.
The result wasn't amazing, but it was enough.

Also, I'm pretty sure you all misunderstand what Jerichai is trying to say, I'm not sure why every seems so eager to argue against his post. Espcially from someone playing SCH, a very busy job whithout clear routine but time restricted abilities. Out of the three healers, SCH really is the partition playing robot with all its CD and 3 time every minute 45s skills to use.
Except when you mess up, everyone die horribly.
