I actually took the time to watch a random portion of the demo around 25k tick mark. Ronnie goes 9 - 0. Issue here at 25k tick mark, well... there was many. The main one was that nobody defended the defuser as he defused. By defending, i mean spraying the loving hell outta him since Ronnie decided to try knifing (terribly by the way).
Vaga's aren't OP at all. Though, this is coming from the guy that played the hell outta Vagalion before and after maxing all races...
We just have to work with what we have at the moment. Once Vagalion comes out - I do intend to play it for a long long while, as long as the rest of my races are maxed before it comes out
