weird, I found a player whose only strategy is to intercepting, he didn't switch at all, in the middle of the match, he was like saying " boring " and quit..
some example:
nokka double account: Riippanokka
qopqo7 double account: 7poqoq
it's kinda fun trying to figure out who is using double accounts to farm cards and levels
meh, player like nokka is a cheater, he uses double account and private match so he can farms K-cards, no wonder some noobs is getting like 60++ wins on a single day..
