What if Kalista's passive....
Was spending stacks ? You have max of 2 stacks at lvl 1 and ** 5 on lvl 18** - stacks need 1 second to charge at any level.
Meaning she can have almost unlimited dashes in a row on level one with no additional Attack Speed and max 7 dashes in a row on level 18 with 2.5 AS.... I think... Or maybe they should be maxed at 4 at level 18....

Anyhow the numbers are just for illustration; I really don have a clue how this will work out (I dont do ADC's), so i wanna hear more experienced players would this do any good on her?
EDIT
The "she cant cancel AA" will have affect only while her stacks are positive.
