Thanks for starting this thread, it might be useful if we had a new one for every month to provide focus on the next round of changes.
Personally I view the basis for card games to be that each player takes a turn to play one card. That was pretty much how Gwent started but now I can play a card and my opponent has the potential to play several cards before I can respond. I don't like this in the game so I'd like to see nerfs to these cards, starting with Golden Nekker.
My 3* provision nerf vote this season goes to Battle Stations. Not sure about others (2*, 1*) though. If the Battle stations stay where they are, I'm gonna vote for them next season again (and again...). I believe this card is one of the biggest developer mistakes. I mean, hey, NG does NOT need any more tempo and thinning. Also slave driver will receive my nerf votes repeatedly, this card is pure s*it and source of annoyance throughout the community.
Nerfing heist also seems like a good idea (or Angus -1power, so he will be easier to remove), but NG is gonna be my main focus for plenty of reasons.
Next nerf candidates definitely are: Mutagenerator, Calveit, Sove
Considering buffs, many ST cards are overpriced so much they are practically unplayable - starting with Milva: Sharpshooter (my 3* prov buff vote). As for others (besides the 4p and 5p elves), maybe some mid-dwarves need some love (Zigrin brothers, Xavier, Paulie), and the movement archetype as a whole is in desprate need of buff - Dryad matron +1 power, Malena +1 power / -1 prov, etc. Movement is one of the least played archetype on ladder (and even Harmony movement is kinda out of the game now). Filavandrel is also overpriced as hell. Also, Saskia: Commander nerf wasn't justified, so I'd like to see her go back to 4 power and 13 provs. That's for the start
