Heroic Omnotron Defense System
Great, another heavy RNG and heavy interrupt fight that terribly favors range. Just what I wanted to see... not. /rogue QQ
What made you guys go to the Trons before Conclave and Maloriak?
One thing that was missed about this encounter which is incredibly important to take into account is that his energy drops significantly faster on heroic mode.
Each construct uses their abilities at relatively static times according to their energy. This results in their abilities being used much more frequently than in normal mode. So not only are you getting used to Nefarian buffing the abilities that are out, but it's also normal mode on hyper speed. Many "this can happen" or "that can happen" situations happen more often than they don't.
For example, when Toxitron and Electron are out at the same time, you'll often be dealing with either the Lightning Conductor being pulled in and hurting the raid, or the Shadow Infusion will be going off while Toxitron is spawning adds.
There's less RNG to the fight than it seems, but it's still a whole lot to keep an eye on.
