Rough drafts of how changes to UI can be made.
(Once skill is charged use your finger to slide the icon to where indicated to active gales speed/push upgrade then release. A normal skill charge without sliding would also result in activating the skill, however minus the speed/push).

And maybe?

(Just in case you prefer how gale works as it is currently).

Your thoughts?
I know for sure some of you mages have considered some way of being able to control this speed since the aoe is very useful but at the same time you don't want to go barging into enemies and taking aggro unnecessarily, especially in pvp.
Cheers!
