My point is exactly what you have mentioned here. Even in a max nano skill setup it is still required to land both drains to use this nano. Furthermore the fact that this nano is out of reach for most balanced setups is further proof in my opinion that the skill requirements should at least be looked at.
I agree that some sacrifice should be made to use top nanos but I feel this is a far stretch when you still need both drains with all Nano Skill buffing Hud/Util items and full Combined Scouts with the Nano Skill buffing Alb Bracer as well full Alpha Symbs.
As I mentioned above I am even fine with needing to land at least one drain to cast this nano but needing both is a bit much in my opinion.
