Thank you very much for your opinion Marot, lesson has been learned now. I'll try to take as many points into consideration whenever judging a rival (I didn't look only Rebounds but I have to admit I didn't study too much my rival).
Talking about winning or losing, I ended my season in first place so I think it has been a pretty good result. Maybe Patience is not as effective in higher divisions, but I can tell you that it nearly make me won my league (I know I didn't win it, and maybe I lost my promotion chances using it, but the season globally has been a success).
Thanks again for the participation and I would like to encourage anyone else who has an opinion to post it on the thread.
