The ADC sounds quite interesting, actually. I'm theorycrafting here, but I wonder if using one of those you could drop other tank mods and swap for more damage mods, at least on armor ships. That way you still have a strong tank for those 20 seconds, but more dps than you usually would. Just make sure you burst down your opponent before it runs out. Buy your CPU implants now!
Basically t3s will be useless in fleet battles why spend 1.2 billion on a Proteus or legion when can fit hacs with these at way less. And just have multiple wings warping in and out during cool downs
Yeah but it's still +15 seconds to your survivability, and also, there are some weapons like RLML/RHML that have limited charges that don't do well when being forced to constantly swap targets.
