So the biggest issue I have recently identified with gameplay across multiple servers is the inability to identify who has made recent investments for industries. It becomes a major point of contention for many different players about "who just broke the majority" of an industry, and the blame game goes on for quite a while in which I have seen players leave the game over it because they just cant take the abuse of being blamed for something they may/may not of done.
What I suggest is that with later versions of the game is that a 3rd tab be added aside the single player and association breakdown of investments which can be in the form of a feed that simply lists investments in chronological order and most importantly labels when a majority was broken/formed, making it easy to figure out where majorities were broken, when they were formed and can give players valuable insight on whether the person is a repeat offender, a new player who broken by accident or multiple investments done at the same time (especially before competitions).
Right now, all majority holders have got is a message stating the majority has been broken and a list of investors in which it is usually quite difficult to identify the culprit of a majority break (its not always the person who invested the most).
Let me know what people think, I'm sure the idea could use some tweaking.
