Rules are ONLY applied in 5vs5 games...
And stats are counted only in 5vs5 games too. Why ? Because some other guys can use this for stats abuse.
Imagine 2 friends want to boost stats, one of them create a " test account " and he let his friend pwn him hard in 1v1 game and vice versa..
This will be so baaad !
1v1 is for fun dude .
