Energy capacities, regeneration, and ability drains have been added to the Advanced Predator Mechanics page and updated on the Predator Classes page. I used the value of 357 for the drain of a full plasma caster shot and frame by frame break downs of regeneration times to do these calculations. 357 full caster drain resulted in mostly clean numbers for everything else.
Interestingly, Scout was an exception in regards to cloak drain and cloak plus thermal drain.
Also, Overload time is equal to the time it takes to fully regenerate the energy bar.
