I really wish the PM team would have made instructional videos for the new advanced techniques, or if it's a brawl player, how to use these already brawl present tech. in a melee enviroment. I'm talking like demonstration videos for wavebouncing (still don't know what this is), DACUS, RAR (this is pretty easy though) and other stuff i don't know about. It would also be incredibly helpful to remake the equvilant of wak's advanced tech. series for melee, this could help all of the new brawl players alot, and they could easily get into melee's enviroment.
Although i'd like demo videos for all characters, the fact that it's still a demo is pretty much why they really haven't bothered to make any instuctional vids for each character (or well that's what i think anyways) considering how long each demo takes to release, and how many changes they have to make, the fact that they should at least have some kind of long-term input from the general public, and analizing tournament results as well, well i would not waste my time making long detailed videos, only to have change the character for the next demo. Plus if you have to many offical videos made by the team about one character, new players could get confused as to what they are looking for or what are they playing.
The other thing would have been combo vids, like lets say the person in charge of thier character (metroid= ike, reflex= wario, Vanguard= lucario etc.) make a starting combo vid when the new demo comes out. It would be cool if they can make it and release it at least 3 days after a new demo is released, plus considering all of the hype, and the amount of people downloading the new demo or looking at the new content, the combo vids released would surely get tons of views, and any new person would be grateful, especially if it's a new character or an already released character that was re-done, because he/she was janky/boring/spamy and the combo vid shows new things about the character and high-lighting those changes. And in my opinion it would look very professional, kinda like how a big company showcases thier product.
