Well since the very day the Borg and Ageis set did hit live most people just go with sets instead of the "usual" stuff, that includes myself.
But after throwing away every engine, shield and deflector for a while now I startet thinking: Is that really the best idea?
Many people combine sets ect... so they are often losing set bonuses anyway. And I was thinking: Couldnt there be better builds with "Uusual" stuff?
Especially now that we have scaling Story mission rewards we get (on fed side) easy access to relativly good MK XI equip.
My Bortas with XII rare positron deflector and XII cap x2 resilient shield (Impulse is the XI Breen) does not appear to be any weaker than my full aegis Ody. But I'm not that a big numbercruncher, so its more gut feeling while tanking borg red-alerts.
