As a returning player, I really appreciate the changes, while I do understand some of the complaints.
I participated in both the closed and open betas, but the gameplay back then didn't really amuse me (I never played Witcher 3 though - I'm only just playing through the second one). This current Gwent speaks much more to me so I play it on a daily basis now.
So from that point of view, these UI/function tweaks were spot on! I'm really happy the round counter is more prevalent, that we have more time to see what happened at the end of each round, that the 'End Turn' button gets chained up when I need to play a card after using an Order, etc. Maybe these things aren't a biggie for people who have been playing for all these years - it is definitely super helpful for us returning players (and, by extension, all the new players as well).
However I do agree with one of the posters here who said that the amount of things that can be done in a player's turn is getting a bit ridiculous. I quite enjoyed the initial ladder experience of almost a card for a card. Now that I got ahead I see things like 'I play a card that plays another card, then activate an Order that plays a third card which destroys another card, all the while my 5 units keep firing away at the enemy'. It's a bit over the top. I'm exaggerating of course. I don't mind the occasional 'play this card that plays another card' (like Affa or the guy who spawns a copy of a bronze Soldier in your hand), but anything above that is a bit counter-productive to what this game is supposed to be, IMHO.
I also feel like some effects could be explained better, like how Armor counts as a Point Value even though it doesn't add to your point total. 'Feelsbadman' when you try to steal a 3 point unit with Sweers just to realize that it isn't really 3 point because it has 1 armor. Maybe Sweers could say: (Melee): "Seize an enemy unit with 3 or less power, including Armor."
