Dont ya go hating on Nightmaher.

She is a valuable asset for any counter team due to the skills she brings. Its BS comparing her to a dedicated counter like Saffron whos entire kit is based around one single thing.
Maher brings several skills to the table including skill activation. which while not as important for a counter team, is still necessary to reach certain damage numbers. Similar to Anemone, Nightmaher is more of a hybrid tank than a pure one.
