I like the Sps reward option, but the problem with that would be that it would forever create extra selling pressure on Sps. Then there is the question of where would that Sps come from since it has a capped supply and the distribution model is already established so the Sps being rewarded would have to come from somewhere in that table leaving less for whatever means it was going to be used for. The Dec drain is the biggest issues, cards will only be cheap for however long they are being printed. It would also not really be fair to handicap someone whose already spent thousands on setting up their bot farms. Dec earnings is one of the bigger structures that entice people to go higher in leagues. Its a touchy subject and there probably is no right answer that would satisfy everyone. But I do think your point of extended search times is a huge pro. If you remove bots we will be searching for battles forever and that in the end would also push people away. Good read.
