it neither stupid or dumb but a curious question(s). Me, I'm treasure hunter so to speak meaning I keep all SSRs Eidolons, weapons, etc.... Here is what learned, Our cap for Eidolons and Weapons is 300(It rises to 400 over in the DMM side). Now If you we're to get every SSR out from the DMM side of things, Weapons will somewhat get close with a good 50 to 100 space left but Eidolons will never reach it. Hell, they won't even reach the half mark. So, it's a matter of do you want to get rid any, I say no cause every Eidolon has a strength and weakness but I also say do what you feel is necessary just make sure you dont regret it.
