I fear for Eldain's growth. He is unitless-ish by nature and with the current frustration of the community for unitless decks, it somehow restricts Eldain's future growth. If the future expansions will add more traps then Eldain will just become the go to leader for unitless. Some player despise him now, what more in the future where there will be more traps? I just played a couple of games with a standard Eldain deck and i don't get GG at all then I switch to unitless Eldain and players are starting to forfeit.
I remember, you were one of the persons who were strictly against the idea of stopping unitless strategies and now you are talking about changing Eldain? Where does this change of mind coming from?
The problem is not Eldain, he is only one part of a superior problem. There must be a limit for special cards, maybe 10 or 15, and the problem with no unit decks is solved, but maybe that is to easy...
This game is based on units and with this change the special cards would take their position as a supporting tool and Eldain will not need a change.
The other problem is the artifact problem. Since the release of Homecoming, artifacts didn't fit in this game and nothing has changed. Artifacts need a entire rework, the way they work now is stupid.
Finally, another problem --> traps. Opinions differ on this question, some people hate traps and don't want them in this game, others like playing them or against them. Fact is, that the number of traps shouldn't rise anymore, because when this happens, you can play roulette instead of gwent. Playing around 20 different traps, it will be a lot fun. But CDPR didn't see this problem upcoming, when they talked about adding more traps to the game...because they never see such problems.
So the thing is not to change Eldain, the thing is to change the problematic parts of the game and most of the problems will be solved.
The question about Eldain's abiltiy is the question about how specific leader abilities should be. Maybe like Crach...very unspecific or like Eldain? Maybe both ways are correct.
