My first thought is everyone will need to put 2 points into gale for the dash ability.

#1 If you die it will help you rejoin the party faster even if you don't use it as your normal 4, you could quickly remap it.
#2 If you get luck elixir or like to farm your movement speed just went up and can do more maps in the same time.

...and of course more crit for every skill is killer
