I think I have said before that I think it is a shame if it is just about money. It is supposed to be a game after all. To get decent returns you need to invest a lot and some people cannot do that. That said, I am just renting and not playing these days, but then I did many thousands of battles. I just decided it was taking up too much time and I had other things I wanted to be doing. I am not into all the options and am not sure I had even seen the pools. I may add something to those.
