bit of a necro but
your speed cant change in mid air so its a good idea to jump constantly if youre expecting incoming cc, especially as druid
for example if you get conc'd in mid air you wont be slowed by it until you land, giving you time to shift out of it and keep moving at full speed
also combine it with back strafing/jumping so you have a chance to dodge cc too
