Ok, probably besides an imminent defeat, why do people quit? I had a Refess player flaming me for half the match (I play as Gowen) and complaining to me that Gowen was overrated and overpowered. I told him I have a second account on Refess and he starts blasting me on having multiple accounts. I didn't get what his problem was but I noticed he was tossing his cards at me in an almost blatant attempt to overrun me. I killed them and started killing his LP. A little bit later, whadda you know? He had a LeBeau as a SS (third one). Goodbye, no unit buffs for you. Then he reveals Guardian Sphinx. I guess his random chucking at me did something - increasing his graveyard. So he brings it out... but I have Berserker out and action skill him. Well, G.Sphinx is gone. I hit his LP again. Another Lebeau but he's got no units. Uhm... then he quit.
Even if your strat is obliterated, I say stick it out, fight fight fight! I've lost all my matches without quitting. Probably half of my wins are quits though. I don't mind quits because I win... duh. But I hate people who quit just because you take the lead. Anyone else agree?
