Some really good points and perspective.
I've enjoyed the changes, I think it gives it a bit of depth now and wanting to keep playing. I do seem to max at 3-4 chests though which seems a little off putting being that the possible is 15. I feel like I'm doing something wrong but from what I have been hearing is it should be impossible to get all of those each day. Idk that seems kind of counter productive in terms of mindset for playing this game. I feel unfulfilled each day nothing maxing it out.
Renting might be worth it if you want to get into that higher tier I still see this causing a big run on cards 48 hours at the end of the season to level up tiers for the next season. It might make someone hold on to rentals for longer though plus they can lock in some better cards and start building their decks through renting. Will be interesting!
