I am still hoping that the GS hit is just a joke or will never happen.
You want to fix a minor problem (cup rentals) and at the same time, we see (heavy) impact on NTs, promoted teams, economy (sic!) and probably a couple of other things we dont think of now.
As a result we will probably see inflation coming back, more NT farm teams, inactive transfer market in the seocnd half of the season, NT coaches ranting about their teams being sabotaged...
There are like a dozen EASY ways of fixing the cup issue, without changing the WHOLE game. The "creative" staff fails once again. I expect this "feature" to become something half-baked like the 5th place fix.
EDIT: not intended to adress manon - just a general rant.
This doesn't only affect Cup purchases, it affects teams tanking all season and then buying a team to avoid relegation and teams buying up a team to win the playoffs. Currently, there is absolutely no negative effects whatsoever from purchasing rental players. If we tilt the slippery slope argument the other direction, without this change teams will simply carry the minimum salary possible as long as possible, use their savings to buy a fleet of rentals, and the whole regular season would be meaningless, ruining the game for everyone.
And the complaints about the impact to the NT are pretty much worthless - the goal of the BB staff should be (and appears to be) working to make the core game experience better and more balanced. So what if the NT is affected? Why are they effected? It's because players NOBODY WANTS OR CAN AFFORD are being created to try to fill NT rosters and then people realize that they can't afford them. It's not like most of them have decent GS to begin with anyhow, since they get bought, play as close to 48 minutes as they can, and move on to their next game.
The "newly promoted" team argument is the one that makes the most sense, and I imagine that it is likely that there will be a window early in the season to allow teams to bring in new players without the hit. But even if there's not, if a team can't manage a minimal GS drop when they're looking to add to their lineup, they don't deserve to stay up in their new league anyhow. If this change actually gets people to put a little more thought into their team-building rather than just looking as the players as assets to be bought and sold, it'd definitely be an improvement.
