while I do love this fit, I believe it really suffers to time against large ephialtes rooms. 3x ephialtes or large ephialtes + karen or benthic combos can end up in very very close timer. Dread guristas launchers / caldari navy launchers are another improvement potential. How do you feel it copes?
I've not had issues running out of time but have not had a worst combo yet, however I've been able to complete all those waves within the 6:40 timer. This does mean it can get closer to the timer yes. Changing the the +3's to +5's will help, using Pyro or slightly better BCS's. However if it gets too expensive it makes more sense to go for the Cerberus is my view.
