When I read your article I was sorry to say that some things sound very very right and sadly they are.
But I personally think we should think in solutions and also there you have already addressed a lot 👍

I got another idea while reading that maybe you could implement to make the game more interesting:
Pack opening Battles (or tournaments).
To play the tournament you need e.g. 5 Chaos Packs.
Before the battle selection everyone gets random cards from these Packs.
And then you have to make something out of them according to the rules.

Alternatively, of course, this is not about pack openings, but about a pool from which everyone gets cards assigned.

The whole thing is of course not thought through to the end, but maybe you can discuss it on SplinterlandsTV, maybe you can find a mouthpiece to the team or some louder players.

In any case, thank you for your commitment to this game!
