@extomar: A macro would be having a single button input the combination for spells on Invoker. Another would be a single button that would automatically cycle through each Meepo casting net.
@noitwont Except the whole reason why you need to invoke spells in the first place is the reason why Invoker has a high skill ceiling. If you take away that aspect of the hero you're literally making it "easy mode" without learning how to play him.
Looks like there are a lot of people here who do not understand the depth behind CS that's developed over the past 15 years. There are several mechanics that aren't displayed out in the open and requires both knowledge and practice to understand and execute.
