they will tell you they want to save time but the real reason is they get very angry and shameful that they lost and quit,you can see that happening more often with better players,I once dueled many players with gold icons(alot from the world champions),and they lose but not let me finish him off,he quits so fast I can't react lol,must have HUGE HUGE EGO!!! hahaha!! feels good man!!
I don't like to surrender either. But it seems like almost everyone else does, especially when: Summon Vision Hero Witch Raider, "Vision Hero Trinity is here!", Activate Beatdown with 3 fur hire ("I'll pulverize you!"), Summon Amazoness Princess (All surrender situations).
Well, there are times when one give up and obviously waiting for opponent to do final blow. The opponent took his own sweet time , doing another e.g. chain of fusion, spells.. combo to overkill, which are unnecessary. Like rubbing salt to wound. Some can be real jerk.
