Because her weapon is so long, her AA range should be increased to 3 and every third basic attack swing should be a lunge for 3.7.
Remove slow from wind up and actually increase speed by 30%. Double the damage on her charge abilities for each hero hit and reset the cd and remove the charge time if she hits more than 3 heroes.
Increase her mount speed after bubble hearth to 250%
Keep her melee hit secured while charging, for balance purposes, but allow her to melee attack while moving while not charging.
Double her run speed after successfully leaping onto an enemy.
Give her armor after landing a successful swing equal to the number of players hit for 4 seconds.
Have successful full charge ally heals increase their run speed and armor for 3 seconds.
There that should do it. Oh and give her a talent that allows her to blink on a short timer on the 1 key.
