Play Battle Art and take a look

Still thinking about applying for the Russian server… I've played the single-player version many times. After level 5, I soloed a level 12 opponent. That guy chose the rebels, just the way I like it. He's the type who plays aggressively in the late game. He didn't expect that I had already built a concentrated central defense missile tower. He just couldn't break through, and instead got hit by my cannons. Afterwards, realizing he was going to lose, he actually quit forcefully… I want to ask, does he get any experience for force quitting? Would it count as a loss? Also, if you lose without force quitting, do you get experience? While playing, can you return to the main menu, and would that be considered force quitting? Does force quitting mean disconnecting or exiting? Do any players know?
