To add to Pike's description:

Personally I find that Long Mode is faster than Short Mode. They are also clearly mode designed for grounded combat as the aerial "O" move is a spinning dive to the ground. Short Mode is better at Aerial combat and mounting due to the bouncing kick.

The combo meter gives an attack boost for each of the 5 fragments you fill up. I don't know their exact values and if they're fixed or Raw-based but I get +360 (200) raw bonus on my Dhisufiroa Tonfas with a full meter.

All attacks can be cancelled (on-ground) into a Run. After an attack's animation you can run straight after. The run has a downside though. At start-up you are unable to perform any evasive movement for the first 2 seconds.

The Jump itself is an overpowered (almost broken) evasion move. Not only does it bypass a lot of hitboxes but it also lasts for ages (relatively spoken). You can evade through moves that were formerly dive-only.
