Yes, I also like the fact that the Meter Burn mechanic works as a hit confirm-only. It's pretty much an option-select.
Also, I forgot the fact that you could give your B3 and F3 a hit of armor using Meter Burn. This gave me an idea, so I hopped on the demo for the sixtieth time and tested out something. You can actually just FADC (Focus Attack Dash Cancel) through projectiles using Meter Burn B3 / F3 instantly this way just like in Street Fighter IV. Depending on the situation, spacing and projectile / character, this can actually help punish certain things, and not just against projectiles alone. This definitely wouldn't be a waste if you could punish and land a huge combo using only one bar of meter to do this. I'll put up a video demonstrating it's usefulness next time I get a chance.
Edit: Just finished making the video. Here are some demonstrations of this "Ground Bounce Dash Cancel" technique I've just come up with. Could be useful for the entire cast in general.
