Most likely the absolute majority would still play FA matches, because it is generally competitive and fun as a group.
However, there is a general consensus that the draws are not fair, which draws a larger percentage and increasingly higher amount of managers deciding to tank for playing only association matches, hence very possibly hurting the income stream of Nordeus from in-app purchases when those managers now can tank for player quality (instead of buying the 8-9* offers, or even buying players in auctions to train with greens [in which TE could earn regular income via ads).
That’s my guestimation of why they finally make changes to FA after not doing anything for so long.
