The bold line is the biggest problem. They have so many good AND cheap cards, while familiar cards from other factions get some restrictions or are a point or couple of PP more expensive. You have even two of those that free you 2 more PP and it is big. You have 4, 5, 6 as SK does and it becomes a nightmare. Like, why was the Svalblod Priest buffed the last patch? An instant 5 points BRONZE engie - what other faction have this? How many resources should I spent to deal with just this card alone? Than you add the dude that halves a unit's STR and deals damage equal to those points, saving you points from tall unit removals.... No other faction has such strong synergies... They have super cheap cards which bring a lot of value due to synergy with their archetype... All faction had got their fair share of good cards (regarding costly gold cards) from CC, and SK got two high tempo proactive cards...
And more and more and more. It's like the devs are adding stuff only to one faction. It's mind boggling.
