Here's a thought: What if Ashe's slow got stronger with each hit?
Since Ashe needs her Frost Shot as it is to save herself from divers, a full conversion to a stacking slow isn't the best option. But then I thought this:
What if the slow started at the same strength as live, but each subsequent hit in a short amount of time made it stronger and stronger?
The problem Ashe has right now is that her slow is not strong enough to be reliable in defensive scenarios. If someone jumps on her, odds are they can tough-out the slow and catch her.
To remedy this, I think Frost Shot's slow should become slightly stronger (i.e. 2/2.5/3/3.5/4% extra slow) with each subsequent hit, up to a cap (i.e. 5 stacks). This would help buff it, but would require that Ashe focus her target to get the rewards.
