2 Options:
1.) System gets implemented and you do not gain (enough) ingame currency through playing, so you HAVE to pay real money to keep your bulletins going if you want to have them all the time (lets exclude commanders, because i doubt that commanders would degrade)
2.) System gets implemented and you DO gain enough ingame currency to sustain your bulletins.
Case 1 is bad, i guess we all agree on that. Case 2 factually doesn't change anything about the status quo, so relic wouldn't get any money. Which case seems more likely?
Option 3: System gets implemented and you get to keep purchased commanders/skins/bulletins forever, or you can use currency earned in game to purchase/upkeep degrading commanders/skins/bulletins. Combined with a whole bunch of cool new stuff.
Relic doesn't alienate people that have already purchased stuff by taking it away, and gives a free avenue for players who don't want to pay for stuff to still get it by playing the game.
Each of these 3 are equally plausible from what little actual information we have.
If you are going to speculate, atleast consider all possible avenues, not just the ones that give you a reason to talk shit about Relic.
