Keep in mind that this is all matchup dependant. Vs a good Arbiter minions are basically useless as example. Jago can handle the minions pretty good as well.
Its not that i hate him for having this tool but this situation does not look good for a spectator that dont know you have to spend the whole meter to get them out.
I will never say Gargos is a easy or OP character cause people still learn how to fight him and tbh not many Gargos players use all of his tools, mobility, normals and stuff. I have so met so many Gargos players that just use Portal punches even vs Gargos and dont block after them.
The portal punch bug atm is pretty annoying - just yesterday i watched flash stream where he lost to someone using that bug as a last way to do something.
Stuff like these bugs need to get fixing asap not until the next character release.
