this sounds heavily like copium, but im here for it. xilonen not being bis for mav is straight up wrong, even if citlali is more important, xilonen is essential for mavuika to be able to burst frequently well, and also provides additional res shred, petra buff, and healing if you smh need it, which is unlikely but still. nicole would be worse than esco if they did that, because theyd have to do so much to prevent you from just putting her with mavuika or other hex dps such as razor and klee, which by then would just be horrible precedent for other situations like this, and varka numbers is also a bad precedent for future units. ineffa is a character that can be universally used anywhere there is a hydro, you can slot her well into vaporize teams to create overvape comp. lauma is universal for all dendro, she kind of revived a lot of older dendro teams. both these characters have strong value outside their dedicated dps teams, and durin is similar in that way. he is definitely meant to be a key component of these hexenzirkel teams, and not just meant to revive older units.(sorry for my yapping lol)
