Um. No.
This shouldn't be posted here and this tier list isn't that great. Ike, Jigglypuff, and Lucina are DEFINITELY not in their proper spots and also, Shulk is a lot better than portrayed. Having "Knowledge" and having "Experience" are two different things that are BOTH needed to properly tier characters. Most people on smashboards have Knowledge of the characters but a LOT of people do NOT have the Experience to cover the other side. For example.
You may be able to GUESS which match up has the greater advantage, by making educated guesses based on things that do consider logic and make sense. This is always a good thing to do. But, we also need the experience, to be able to have seen it in action in order to confirm we are right or wrong. In a sense, you can make a really good hypothesis but it is still a hypothesis. Otherwise, I do appreciate you for studying videos and using some experience and generally making a pleasing video to watch.
Other than my disagreements, as of right now, nobody has enough experience to properly place characters into proper tiers.
TL;DR: We haven't seen every single match up in this game to a point where we can make a tier list, as we would have to study the match ups, make predictions, test these predictions, and make conclusions with logic, fact, and excellent reasoning.
