As I already written in thw WIP version (I'm talking about haunted forrest): nerfing upgrades didn't help the tier 2 that much, as it effectively also nerfs tier 2, i think that making different cards upgrade in different ways would make things better, and maybe more interesting as well. The other option is drastically decreasing the tier 2 packs cost, as it can be hard to gain enough of them to do much upgrading. From the other things I woul really love to see some better way of upgrading (filter for upgradeable cards for example). Beyond that the game is very interesting and has a lot of potential, so I hope to see it succeed
Making upgrades weaker and weaker doesn't improve viability of the tier 2 much, because it also is weaker then, I think it'd be best if the cost of the tier 2 was decreased, or the way leveling works was changed (for example different cards could be upgraded different amounts, or in different ways, which could also make the game more interesting and introduce possibility of different optimal strategies appearing as the cards are upgraded).
It's sad that there is no connection between different realms; it would be cooler if opening new realm would expand on what the previous one offered not completely replace it.
My original goal was to have them be their own separate things, kinda like in Supply Chain Idle, but something I'm considering now is to have Haunted Woods's shop eventually give you the ability to purchase some unique cards that get sent over to Intro Realm. Still trying to figure out how that all should work.
