Hehe yup I agree! I didn't really invest in the game except for the spellbook and it was easier to get up to speed back then because there were reward cards and no starter card penalties too. Nice ROI from timing of the SPS!
On Vouchers, yeah I guess the only route to "encash" is to swap for those cards when I have enough.
Yeah it's a lot of fun still, and I think it's more fun and less stressful to "ignore" the earnings aspect, otherwise, it's very easy to be disappointed at the outcome.
Thanks for sharing your view too!
