So I've recently started messing around with the trait "Overwhelming force" which creates photonic shockwaves when you hit a target with a high yield torp, I also recently got a ship capable of using concentrate firepower III, which gives your torps high yield and resets their cooldowns. Also, if you use an AOE torp with it, it creates a LOT of shockwaves vs groups, so here's what I was thinking: Group them up, hold them in place, and then spam high yield hyper plasma torps at them to hit them with like 100 photonic shockwaves for collosal damage. The problem is that with this ability (And others like delayed overload cascade), even though it has the potential to do large damage, it's not worth it because it knocks them across the map and ungroups them. With this technique, even with grav well III and grav torp spread III to hold them in place, it knocks them like 17 KM away with neutronic torp, and pretty far away with hyper plasma torps. Also, higher control expertise for my grav well wouldn't help because it'd also affect the photonic shockwave's repel.
Basically, I need a CRAZY good way to hold stuff in place. Preferably a way to put stuff in their way so they physically can't escape the area no matter how hard I blast them out of it, that way I can keep them stuck there getting bombarded by this endlessly. Also, I don't use super duper expensive stuff like 900 million EC ship traits and stuff. lol
