Maybe they should buff Tissaia der Vries a bit. In the beginning I was considering to be very strong but after playing her I have to admit that she has only Meme potential. She only offers huge value if you have a long round with many surviving order/patience units and this is only rarely the case. And if its the case there is a high probability that you would win the round otherwise.
Deploy (Melee): At the end of this turn, reset the Order of all allied Mages that used their Order during this turn.
Deploy (Ranged): Generate a copy of an allied Aretuza unit (Aretuza student, Aretuza adept). Then boost self dependent on the number of Aretuza units you control.
=> Her Ranged would have significantly less value potential than her Melee. Furthermore it´s still kind of conditional fitting to the overall idea of PoP (high-risk -> high reward)
