As a SY player i am losing interest in playing more gwent for a few months because of the horrible state SY is right now. Here are my main reasons:
1-The new cards were bugged for a whole week while the rest of the factions worked without a problem.
2- The nerf of Shady Vendor and Conjurer Candle was a HUGE hit for SY both of these cards were/are used in many decks and right now candle seems unplayable.
3-New cards are good but they need a lot of setup to work, soo you are forced to use either bad cards or cards with no synergy. In my experience and watching streamers collusion doesnt work right now as a competitive archtype.
4-SY cards in general feel more powercreept every new patch especially the 4-5 provision bronzes. I am pretty sure a spotter gives you more points in average than 2 syndicate bronzes combined.
Sorry for the rant but i really want to enjoy the game and right now SY feels like i am playing on hard mode.
