Cesare was doing Borillo + Ivan rushes. I don't remember it being an issue, though (at least for me) since people were walling their structures most of the time anyway. Even if he destroyed few structures, the game could still go on.None of us spammed Borillos. We just used them for Engineer Rushes...
The Borillo & Wolfhound Rush didn't become apparent till Public BR1
I think Stallion Siege Cadres drops caused more issues.
Wolfhound issue was noticed. They were already nerfed during the closed beta times (2 times, i think). We didn't get much issues with them, though, since apart for team and vs AI games, most of the time nobody even had the time to get a critical mass of them.
Or people simply learned how to counter it, so the Borillo Rushers moved to someting else.Not many people even seem to use the Borillo tactic now, they must be preparing for the update... Good
Nope nevermind, borillo rushing is still alive and well.
