We just have to make the most of the new system and have fun while doing it. I just play the game like I always have, fighting to keep my town Mystic. I don't participate in or condone making "deals" with other teams just to get "my 50". If valor takes my gym down, and I get my 50 coins, good. If not, I'll just travel to Valors' territory and take some gyms down there to get my 50. I think this system actually encourages more competitiveness than the old system, if you have the right mindset.
