There are so many options to get the deathblow or bloodthirst how can you say it's not easy?If you play with blood eagle you'll realise the conditions are not that easy, most of the time you want to instantly use blood eagle, mainly to pull Skjordal for a quick kill on a Engine or something, which is going to be more difficult.
Anyway I'm surprised by the quick Nerf, Can't tell how hard it's going to hit SK, but it's a little annoying that most factions get hotfixed, apparently the ones that are mostly weak throughout the year, but when it comes to certain factions we have to wait seasons for a nerf.
I believe like the others prov limit is a good way to balance these Leaders, Nothing equals to playing These high prov cards twice basically.
This is the only faction specific echo card that consistently tutors their evolve card and it's a measly 10 provisions, ridiculous. I have yet to see a Skellige player struggling to pull this card off, it's practically guaranteed. Not difficult at all.
