Gilgamesh's importance in Ashblade teams

I'm talking about both E0S1 and E1S1 Gilgamesh (As I think his S1 will be "free", and I alr have Archer's S1).

I don't particularly like Gilgamesh, due to some things I heard online about him being misogynistic and some similar immortal stuff, I get he's a villain etc..., but I don't like having someone like that, if that is true, in my teams, but that aside, I really really really like his kit, and, I know it may sound stupid, I always wanted a team that could hit 100% def shred, and with Ashveil's 40% and Blade's 30%, Gilgamesh at E0 would hit the 100% def shred perfectly, and with E1, he would give the 30% def shred to the team.

I don't have Tribbie rn, so I usually use either RMC or Sunday (Speed tuned with Ashveil) in the team, while Blade is on 4pc Eagle, both Ashveil and Blade are E0S0. I also wanna clarify that if Aventurine turns out to be the FuA main dps that some leakers hinted at, I won't have a problem at grabbing Archer's E1 over Gilgamesh, but I would still like to know how good he is etc... since Aventurine's beta is in so many days, that I need to know at least about Gilgamesh's place in the team
