Just thought of it and had to ask first

Would Eviscerate proc the chain lightning damage from Storm Claw if you activate it before entering melee? I just want to try out some different things so I threw it out there.
Stormclaw's tooltip explicitly states "Requires base melee weapon attacks to trigger". "Base" attacks are basically auto-attacks. While "melee" applies to any %WDPS skill cast while using a melee weapon (OR, an auto attack for that matter), "base" will only proc on auto-attacks, ie. right click. Take note that Stormclaw may still come in useful if you run something like Ravage and start auto attacking when you run out of mana. Xkilla does (or did) that in his Ravage video.
TL;DR: No, Stormclaw's "right-click-only".
