99% of the time I play 3v3. In annihilate games I notice nid players either go carny spam or ravenor spam. I find an apoth with missle tacs take out carnies fine. But as SM how do you take out a full ravenor spam short of an OB. I think nids are DOW 2 on easy mode as it is. But 15+ ravenors burrowing around under the ground then popping up behind a bases defenses is just ridiculous. Any suggestions?
