No one uses level 3 6ER over level 4 SNR. The vacuums are worthless, drop a tank when the vacuum gets to your side, wait for their wave to get there, then burst him down. Not worth it to summon when 6ER is in a fight with the animation time to spawn the vacuum. SNR summons are comparable to assassins and take little time to summon. Already said GWC is a tie for worst with awesumo. At the end of the day Awesumo is exceedingly easy to counter. High cost makes him a smart target for instant kills. His health isn't high enough to survive a solid burst. Any one using him over zen or sherriff doesn't know what they are doing when playing mystic. As far as BHK he is easily countered. If you have trouble with him you need better counters to flying and likely rely too heavily on swarm cards. A well timed ninjew is vastly superior.
