After playing many battles in 10min format, I think that this is a bad change. In 10min battles the game became boring. I've seen the following problems again and again during these 2 days. 1) Many times, there is a team that makes 1 cap quickly. So the players of losing team start to exit the map. It makes the round unbalanced and the round ends early. Also the crystals are not so many. 2) If one team has less players and loses, new players don't join the game because of lack of time for a winning comeback. 3) GB doesn't fall so often. 4) Because of the problem (1), there are no battles that the 2 team fight for the win till the end. Personally, I've played only 1 battle that was a derby till the end. So, in conclusion, the battles became boring. Also, there is a big decrease of true battle time(3-4 min out of 10) of strategy, killings and tries of capturing, because when a team gets the lead, the losing players start to leave the battle and the battle ends. While in 15min battles, the true battle time was almost 10 min(or more) of 15. I think it's the worst change in battles. It's worse than the change that only pro-players can create battle(which change made many maps "die").
