True, but Eist + Blaze of Glory is worth a lot of points and without Blaze of Glory you need to completely replace Eist with some other Gold, while Patricidal Fury is basically just a 3 point buff to Sove, which is good regardless and only slightly better with Patricidal Fury (unless you run Ulula, but in that case you need more time for setup). In fact Ulula has anti-synergy with Patricidal Fury in that she will kill the Sirens if one does not play Patricidal Fury in advance, which is also giving up on more flexibility.But right now you run Blaze literally for Eist-Jutta and nothing else in the deck. There is no special synergy between Blaze and warriors.
The difference is that with Patricidal Fury you lose an entire power play, while giving up on that leader ability costs you very little.
Maybe the revealed change to Patricidal Fury to go to 12 power will buff it enough so that it is still worth it, but I would say Blaze of Glory is still better.
I am not sure about that, given that the Devotion wording almost specifically includes the way he gets used.And in fact, you can actually play Eist with Patricide, which is probably how he was designed to be played, because the devs as usual did not foresee the cheese.
Edit: Who knows, maybe I needlessly dismiss more engine focused Bloodthirst builds that would run Patricidal Fury, however right now I do not think there are enough payoffs for that to be worth it.
