And how does the onboarding of new players go? I mean... if I remember correctly, I saw some stats about pack sales and new users in the mav's house. It could be I missed it, but I haven't seen any stats since. While I'm actually really interested in how they are doing when it comes to attracting new players (not alts).

I assume it is not a priority yet, since they are still tweaking and trying to find the right balance. But since they've posted an announcement that they were looking for advertisers and sponsors, I think expanding the userbase is either happening, or at least should become a priority.
The fact that they need bots to make sure that the gameplay isn't interrupted, because "there aren't enough people playing at every level on any moment during the day" (not an assumption of mine, but a quote from Matt), doesn't sound like they are onboarding a lot of people.

(I'd really love to see some stats, about everything, to get a better ida of how things are developing. Just out of curiosity)

I agree that the reward cards would indeed serve a better purpose when used to make new players hooked and get them to buy packs, definitely now the reward cards - once all are released - ar going to be a worthy deck...

But again, my battle about things being fair or not, or if things are a smart or a not so smart thing to do is over. It's their game, so they do as they please. I'm not a mav, so whatever I say doesn't matter. And the only thing I achieve is getting into endless discussions and getting downvoted.

Time to let go and move on. There is no use in wasting energy trying to change things I can't change. So for the moment, I don't care anymore about who gets how many reward cards or no reward cards at all. I'm just going to play my games for fun, cutting down on the time I spend doing so. That will give me a chance to become more active in the community again. Planning to keep my highest deck in place, and thinking of putting up everything else up for sale.

I don't have any energy left to waste on a game. There are plenty of other things, more important things, that are worth the energy I've been putting in.
