I am not a fan of the survival mode. I think it is a wrong priority for the game now. It has no appeal for new players, and not for the majority of players who rent/own one deck with single copies of each card.
Sure, this brings additional utility for owning a lot of cards, but there are less time-consuming development options available for achieving that, like lowering the DEC stake needed for land to make that more about owning cards than owning DEC, or implementing that infinite land card staking thing we heard about (what a year ago or so?).
I'd rather see time spent on NPE, bringing leagues back and most importantly: Focusing on GUILDS!
I agree, it probably wont appeal to new players. At this point, I'm not sure what will?
Guilds are great if you can find like-minded folks! Not always possible for some of us. I'm in a guild of 1 person, only so I can get the guild bonus. Other than the bonus, I don't think a lot about guilds anymore. It's kind of sad 😌
