Sterak's Gage shows (+0 AD) gained on shape-shifter champs while still giving AD

Basically what the title says. The item's tooltip does not really suggest that the AD would be melee-only however the stats shown are misleading. While calculating the AD it's giving you is not really a difficult task, it does cause clarity issues. I would assume that shape-shifter champs getting the AD is intentional so I'm just going to report the text bug that shows that the item is giving +0 AD instead of the appropriate amount. This is consistent through other shape-shifter champs such as Jayce.
