I agree that fun decks with alot of niche synergies are not necessarily competitive, but the person I quoted said in his first sentence that he is just an average player and he did not see anything fun in when he opened the deckbuilder. I cannot talk about the competitive side of the game too much since I never reached the pro ladder or anything like that, but I just cannot stomach all the thoughtless "everything is add points or remove points" and "there are no fun synergies" pseudo-arguments. Personally I am having more fun in the Gwent Homecoming than in Gwent post Midwinter (only saying midwinter because I honestly do not remember the level of enjoyment I got from the game before that). However, I do acknowledge that there are problems that need to be solved but in my opinion the Homecoming foundation is stronger than the pre-Homecoming one.It should be added that most people talking about strategy and such are talking about competitive stuff.
Sure, you can build a lot of decks with a lot of fun little interactions, but if those decks aren't good enough in a competitive environment, the entire point is moot.
For example, in beta I had this fun little Kaedweni Revenant Swarm deck. It was a blast to play, had a lot of synergies (Henselt-Revenant-Siege Support-Flails-etc.) but it had a winratio of about 40%, so the deck was pretty much irrelevant to any discussion about strategy in Gwent, it couldn't win consistently and it certainly couldn't beat the meta (apart from consume Nekkers).
A good example for how one dimensional strategy in Gwent is, are the tournaments: how often did the person win, that targeted a specific deck he knew his opponents were running? I think last open Freddybabes demonstrated this perfectly, iirc he always won 3-2 making 4 decks that could beat the 1 deck every other guy was running and basically forfeiting to the other 2 decks.
