I got the game recently and this is just me doing some practice. Figured it'd be a good video for those that want to see how the characters generally work. Note that I'm not really in the swing of things yet - I've only got a couple of hours in and haven't played a game like this in a while (been passing the time with Garry's Mod lately, which is just a fundamentally different kind of game).
I don't think I'm very impartial to any character, but I suppose if I had to choose it'd be: #1 Blake #2 Yang #3 Weiss #4 Ruby. I'm guessing it's because Blake is the most agile/aerobatic feeling and Yang is a fast boxer, both which suits me quite well (see my other videos from ARPGs - it should become quite obvious that I go for speed/agility types).
However, that ONLY applies to SINGLE PLAYER. In a group scenario I think the other classes have their roles, but only to a slight extent. They're mostly similar though.
But I really don't have a huge preference, they all move quite fluidly and even the clunkiest isn't actually clunky to any meaningful measure.
NOTE: This is the lowest graphics quality the game has, because my computer really needs replaced.
