In the past never really had any issues with the turret dreadnought, but lately with the rework it starting to turn into a gamble… sometimes its easy ish, other times its insanely hard even with a good mix of Engi/Guard Frigs.
The spawns are so numerous, and their attack patterns is just luck… i mean if they spead out evenly your fine, but if the mass on 1 target he dead with no hope, once one goes down rest soo follow.
It just seem to me the number of ships is just too much, would be better to send less ship but tougher ships, which will maintain the challenge, but not be a npc dps overkill.
