No, even unbuffed - the map does not have enough gold to go for left, center and right, so a lot of infs face no opposition unless your adversary knows you have the card.
I think enlist 4 would be far better there than enlist 7
1 left, 1 mid, 2 right seems the best combo so far
Maybe another one on left might be good but anymore than that seems you can only get either left or side or maybe none at all
One recon can make the right side cry and since usually people going for left with quite some unit left seems pretty easy to cry too
