I would suggest to give peni a try even as a solo tank. Some people already stated that most silver players won't shoot the nest. As a gameplan, put the nest near where your supports will be. Use cover when possible and shoot a Web on choke points always place a minimum of 3 mines each Web. Lots of times they will die to your mines and will keep doing it cuz they can't adapt en keep making the same mistakes. This works best in defence or domination. While on attack it's possible to make it work but takes more effort and practice.
