Fatboss is amazing. When they stopped doing guides for a while I looked around for alternatives, but most of them were awful compared to fatboss. Evrelia seemed cool (because he sounds like fatboss maybe). Expanding on what Treelife said, almost all other alternatives present tactics in a way too long fashion and either have tedious voices or europeans with awful grammar and pronunciation explaining them. The fatboss guys are fun to listen to and are pretty good on focusing what's actually important in an encounter.
