Investing in special routes on Europe scenario is kind of wild, people having few millions investments, do auction each other by 10k or 20k like many times, time after time again just to be ahead.
In industries there are specific amounts of money, which get higher after every click. It's less wild way needing less of attention and often refreshing and checking the investments there. More comfortable, less time consuming and less sever capacity consuming.
Why don't we do same with special routes? The one who invested sooner, same amount is higher and investment amount are set automaticly as in industries?
That would save time for players to check special routes so often and would save some server overload a bit too.
