I was actually considering making the mechanic even more complex and even closer to Magicka than the Invoker - you can hold R to charge the spell (like Varus and Vi). At the moment this wouldn't work with all his combos, but it was just something I was thinking about. Maybe Groundwell's damage increases as he charges, and the cast time is instant once he lets go of R - so you can see him charging, and no that he's about to fire it. *shrugs* This is probably entering the realm of stupid. ;)

With only my superficial understanding of the Invoker, why does he use the "save" system? The nature of a queue means that it pushes the oldest one off, which means if you cast a stun and then follow it up with some damage, you can not only use that damage ability if you want to keep the stun in the quick-cast slot. Seems overly complex to require 2-buttons where only one button suffices - unless he has a 2-spell, short cooldown combo that people just press D-F-D-F-D-F repeatedly.
