I don't think the same time process thing will be fair with so many countries and timezones present. Plus it still has the issue of people that have busy schedules (school, work, friends, trying to eat somewhere in there) would still be at a great disadvantage, probably more so depending on the time.
The X bid(s) per Y, I like. It makes sense, an organization would have to talk things over. Along with raising the increases, but their would have to be a ceiling (1.8 million @ 40 percent could be ridiculous) but 100,000 raised each bid would not.
I still think charging per bid would be beneficial and make managers decided how much they want to spend instead of trying to nickel and dime their way around.
Honestly I hate how much this game seems to revolve around free agency, but there is no way to be competitive without using it, especially early it seems.
