3-4 msmg depending on preference
I posted showing both ways er adaptations to this idea
I prefer using the 3 msmg for extra defense
the 4 msmg version is only playable with a medic
I also wanted to show off more of these pyramid pieces they are so interesting for giving angles to a build, basically just a tetra but with an extra angle or dimension added on.
If you would like to try this build plz ask in comments below
Then I will post it
