This isn't a strategy guide or player-made guide.
you don't even follow the probuild correctly, the 'probuild' is not 2:1, if you must know it was originally 3:1 then brought into single squads as 7:3. The point was to be above 2:1, but 3:1 doesn't work out as nicely as 7:3, and 7:3 is easier to adapt to single squads.
do remember though, that this was a quick, quick test i ran.
with not exact numbers.
but your still missing the point, which is i bet if someone really wanted to, they cold find a better build then the probuild with damage units..
No.. You really can't incorporate damage units successfully in a build. The problem is that the whole idea behind the 'probuild' is to not go past round 1. The DESIGN of the build is to force a round 1 kill (or round 3 depending how much r5 you have).
So really.. the only type of build that could 1-up it would be a better balance of the 7:3. Like I said.. you can go between 7:3 and 3:1 but lower than 7:3 and you're range light. Higher than 3:1 you're armor light. However, anything in between those 2 ratios would not be easy to manage in squads.
