I use legacy keys for all my heroes because of how much Dota 1 I've played. However, in the one week that invoker didn't have legacy keys, I got really used to non-legacy keys for him, and I actually prefer them to his legacy keyset now.
I was wondering if there's a way to remap invokers skills to have the legacy key checkbox still active in settings (so things like courier skills are still legacy) but have invoker's invoked skills still go to their defaults (d for latest skill and f for second latest skill invoked). If not, would it be possible to add such a feature? (I know how important total customization is to Valve.)
