How is this a skill issue? At no point did I say I lose the mirror matches. I just don’t like them.
About your whole playing Kil’Jaeden first paragraph: I know it is more nuanced than that, it is obviously oversimplified, because it is a bullet point in a list!
Also some of you points don’t work out in practice. Yes, in a Starship DK mirror, playing Kil’Jaeden too early can kill you. (Unless your opponent played almost no Starship pieces yet and you are certain you get big demons before he has a starship ready. It also depends on your hand, and what cards either of you have played already. Again, I do acknowlegde their is nuance here. Too much nuance to put it an a freakin’ bullet point.)
However, in practice often both players summon their starships, clear the other ones starship, and then you have the Kil’Jaeden battle again. Or some starship-randomness decides the game. If one gets Dungar and one gets Wakener of Souls, that can decide a game.
Your paragraph about Protoss Mage is odd, because they (usually) don’t even play Kil’Jaeden, and you (usually) don’t use it. Unless you’re playing Control DK, without starships. Yes there is more nuance here too.
About cutting Kil’Jaeden from control Warrior: True. I cut Kil’Jaeden from all but 1 Warrior list. I hope the card becomes worse in the future. Unfortunately most control decks are DK and the ones I’m playing most tend to be too. Deathknight atm feels like “Warrior but better”. (Before you say anything, this is also oversimplified on purpose.)
We can now talk about even more nuances in specific matchups, but that actually just distracts more from the topic than it adds. I just made an oversimplified list to show general tendencies. That’s it and you don’t need to interpret anything more into it.
My point is: When fatigue still existed, the player who spent his resources more carefully won. I think that made mirrors more interesting. You had to plan towards the end of the game for the whole game. I liked that.
