So many tier lists put them above prx, te, etc. They are still shit.. Primmie is good but we know one guy can't carry. Mei couldn't do shit last year.
SEN should be like bottom of S, probably closer to top A. It just depends on if they stick with the role swap and if they can make it work or not. If it doesn't work at the next off season event, then just give up on it and go back to comfort roles. Or just make Zellsis play senti/lurk so then n4rrate can play with the pack (I think this makes more sense anyway).
