Interestingly enough dropping rewards to like 4 or 5% and giving unlimited BA would end a lot of the reasons for people complaining about the way the game currently works. Of course you would have to scrap the n*b system.
It would also encourage bots, and IIRC the main reason Jon put the BA cap/limit in place originally (I think BA used to be unlimited) was that it makes those with the fastest connection, and who could click 'fight' the fastest win.
Which isn't good.
