Ashe interactions with new crit items

Some of this might change before release but here are some things I found in practice tool.

Stormrazor:

• Volley always crits on champs (it applies the enhanced slow) which counts as a crit for Stormrazor, so it activates the MS/AS buff.
• All individual arrows from Ranger's Focus have an individual chance to crit, so it allows her to keep Stormrazor's buff going easily with only a Zeal.
• The free crit from Stormrazor makes her apply the enhanced slow. (obvious but here for completeness)

Infinity Edge:

• Volley gets the 20% true damage against champions because it always crits against champions.
• Basic attacks only get the 20% true damage when you roll an enhanced slow crit. (obvious but here for completeness)

It makes me think Stormrazor will be a good buy on her. She can easily make use of the AS and MS. Simply getting 8% MS from hitting Volley is awesome for her. The attack speed buff is really strong when you can keep it going all the time, which you can with only a Zeal during Ranger's Focus, and you can also refresh the buff with Volley.
