Yeah it's not great that they've massively changed things yet again, but I wasn't happy when they brought IPDs in in the first place because it makes it a short term game rather than long term, so I'm reasonably happy. The reasoning behind it makes perfect sense, it would be difficult for prices to rise back to where they were when everyone is selling when a player scores a goal so they can refresh their shares. They did say a while ago that IPDs are confirmed for the rest of the season, not just as a promo though, and understandably a lot of people are pissed off with yet another u-turn.
I'm just sitting back and watching. There's no use in panicking. They say they're gonna replace IPDs with something else, tiered PB or payouts for certain levels of PB scores would be great. I can't help but think they should have announced what they're replacing it with at the same time and save a lot of drama though.
