Cap boosters negate the ability to neut these ships out effectively. As long as they’ve got boosters, they can survive. It’s worse in WHs.
This kind of thing should not happen: Minokawa | Holmsey | Killmail | zKillboard - reps 6 mill actual damage against a 150+ man subcap fleet for close to twenty minutes until dreads could be brought in range. That’s OP, and forces escalations when they shouldn’t be necessary.
