Don't put an exotic mod mockup in the thumbnail unless the video actually has something to do with exotic mods. Don't create some mockup of a fake exotic weapon and slap that in the thumbnail. Don't put an exotic from D1 in the thumbnail of a video unless that video confirms the return of that weapon. If your video is about discussing stuff that's been revealed, DON'T put shit that hasn't been revealed in the goddamn thumbnail! It gets people's hopes up and it is annoying as -blam!-!
