They all move relatively the same, but each class does have different jumps. With the builds we're allowed to play with, they are as follows: The Hunter has a cool Double Jump that can be upgraded into a Triple Jump with enough playtime. The Warlock jumps and sort of hovers in the air which is a good way to get above the battlefield for a short while. The Titan jumps very high and floats upward like he's wearing a jet pack.
