Playing solo is basically impossible. I've pretty much everything I can think of. If you smoke garage, they run through. If you molly garage, they smoke it and run through. If you molly boost they just come from garage.
Of course if 1 or 2 people are taking mid, it's do-able, but recently people in my games have just started to rush mid with 4 or 5 guys. You cannot hold that solo no matter what you do.
