I think we should be able to restart our games on our devices knowing that our gems will be lost we won't save any loot and all trophies will be deducted. The trophy thing is an issue though, because that would imbalance who had and don't have trophies. I recommend that when you restart your game the trophies you have are spread through the game for example: bob raids jimmy for 20 trophies and gets one hundred percent. He earns twenty one trophies because of me restarting the game and dispersing my trophies all over. This happens over and over until all of my trophies are equally dispersed among random people. Another option is you can't restart your game unless you are at 0 trophies. THis is my opinion and hopefully this happens in future updates. Like or comment if you agree or have ideas on the topic.
Wont' work - because over the course of the game you might raid 10,000 or more trophies. So how would those be distributed if you only had 1,200 trophies when you reset? Also ruled out anyways.
