I voted for all, because combat needs more options.
I would even go one step further, and suggest that specific mechs should get specific movement mechanics. Jump jet, ramming jets, extended floating, blinking, whatever - while keeping the same core moveset, allowing for balancing (obviously the blinker shouldn't also have the same dodge cooldown). Before people start crying foul, there are plenty of examples of games with class-differing movement, all of them Korean, and very fun and deep from what I remember. 
[If you are interested in examples, there is this little gem called Rakion, that was a marvel to play before it went much too far down the p2w path]
I mention this not as a seperate suggestion, but just to illustrate the point that this is just the tip of the potential iceberg in enhanced mechanics, and that we should explore all three options to see where it could potentially lead.
Right now, the only facet of HAWKEN movement that remains unexplored I feel is the repair-cancel. The reason this is unexplored is because it is currently the 'most meta' move, and there are very few opportunities to use it. Also the margin for effective execution is quite slim, but given the recent splash changes this might change - hopefully the skilled player base has not got lazy and comfortable rolling around in HEAT Scouts or leveling up Cs to experiment ^ ^" .
