NR has extreme combos,if you let their units sit on the board...it gets BAD fast. If a bare minimum of half your deck has to be sedicated to crappy units that can't get rid of them before a 30 point combo happens, you enter scoop phase.I'd agree with him/her but for different reasons. Ramping up easy, on-demand tempo (point-slam) to counter control has it's own problems. It should not be a matter of providing this to make control non-viable. It should be a matter of non-control based decks having the ability to actually keep stuff on the board against control. In other words, the two concepts should be competitive instead of one-sided. There are a lot of ways to accomplish it.
The problem with making these two concepts competitive against each other is doing it in a good way. Right now, and for all of HC, key engine and combo pieces run away with a round when they work. They don't all do this but even a bronze engine can rack up points well above it's cost in a long round when it sticks. Incidentally, people complain about binary game play. Remove all of these cards or else. It would be a much better system if the cards you want to control had less ability to snowball a round and the control cards had less ability to instantly kick them off the board.
Spamming specials and artifacts isn't the only way to play a control build. It's not like these special/artifact spam decks have ever been top tier. The complaints directed at them have never been because they were strong builds.
In terms of SK/NR.... Meh... SK has pretty much always been top tier. It's the faction identity . I fail to see why knocking the artifact/special spammers down a peg means NR will magically run away with things. Even if they did it won't be the end of the world if NR is OP for once.
It makes the game excessively binary.
1, 2, 3 or 4 unit decks were a problem but frankly, removing them also removes a barrier of entry to top tier for NR and makes Skellige even more out of control.
At this point, I don't think the devs have any clue about TCGs. This is pre HC monster consume waiting to happen all over again.
