I never really was into buying packs, I've been playing since the beta set and didn't get those or the untamed packs, instead always waiting for when the market was down to pick cards from the market cheap while earning reward cards. I did get tempted by the airdrop system to buy 610 Chaos Legion packs which turned out to be a pretty bad deal. In the end, more players always need to come in to keep the prices up and create a boom cycle. I'm hoping / anticipating there will be 1 more big adoption at some point which likely will be the time to just take profit.
I don't intend to buy any rebellion packs and they need to find one way or another for players to have incentives to buy them. The only really thing that works is to have a situation where earnings justify it. Last times they always just created a new token to have this happen, first DEC and once that crashed SPS with Vouchers which both also crashed. I assume they will introduce some crazy power creep with rebellion so players who want to win need these cards. There is no point for new players to buy expensive rebellion packs if there are cheap chaos legion packs and cards on the market. This makes me want to pick up some more cards at current prices on the market.
That being said, I still have quite some confidence things will improve as the game it good enough to at least attract more real players.
