donating makes animating financially viable, and having animation be a viable finance allows him to dedicate more time, which turns into more frequent uploads
"hey guys i have a patreon now go ahead and join for some cool content, okay see you next video" nah lets animate 50 seconds of smooth animation, introducing a new character, all while providing some slick and flashy visuals all leading up to the patreon logo. nothing more is needed.
A bit too early to ask for such a thing in my opinion...I could really see him going somewhere if he uploaded more frequently. I know animating is difficult but I just don't know if he'd get anywhere otherwise.
