Armor Lock is a mulligan. There're no mulligans in real competitions! Invis is for cowards. They are all fun and great... but not balanced... so leave them out of ranked as much as possible, especially 2v2 because that is where they make even more of a negative impact on the fair gameplay. And my silly gamertag is not as weak as some tool that needs power ups to compensate for his inferior aim and reflexes.
