you know, when I saw this. I think it look very brilliantRewards to players for each month they subscribe rather than charging extra money on top of the sub fee for cool things.
now they only hav to release super cool reward every 90 day
here my opinion about this
sub base game : 30day reward - "ummm" // 60day reward - "cool" // 90day reward - "DAMN it look cool i want it now *sub for 90 day*"
free to play game : here the cosmetic item for this month 5$ // next mount 10$ // super cool cosmetic item/mount 15$ *choose 1-2 from list maybe
what i saw is that "this reward system" look very promising i feel like it can keep sub base game longer before free to play take over
