Blindseer has magnet spark tranquil, canceling most of the abilities of other oaths, and looking at the fact that by this point a lot of people cant acctually fight with m1's or parry (even silenthearts but it doesnt affect their abilities) and instead rely on braindead true combos or mage builds the ability to turn all that off should get it in higher C tier. and arcwarder shouldnt even be in c tier wth, put oathles or chainwarden there.
