Purge's Guide to Ganking and Roaming

This is my inclusive guide to Ganking and Roaming. I spent a lot of time on it, so I hope you find it valuable. I know there is crap loads of information here(arguably too much) but I wanted to make sure that pretty much everything was covered. Also, I suck at editing video, and this was my first time, so sorry for that, I know it could be smoother. Enjoy, and share with your friends!
