I have one skill too, Deadly Strike, and I can't use it while on mount, tell me please why you should use stun/hydro blast and also WHY you should be able to give 300 speed to your pony ? because your mount gives speed bonus for 30 seconds to your pony.
I'm not saying you are OP impossible to kill. I am stressing the point that NO OTHER class is able to use ANY skills while on mount but you can use and not just 1.
The votes are in but this isn't a priority thingy, so we will have to wait for it more.
