Dredge Anchor moves fast enough to hook Drogoz right out of the sky, and his weapons deal self damage, so hook him down and he's vulnerable to you and your supports.
when he jumps up in the air try to hook him down, he can do a lot more when he is above averyone. also he doesnt have any escape ability left after that.
Makoa can shut you down VERY easily with a simple hook. Let your team bait his hook, or wait it out, then focus him down from above. He has a tiny chance of hitting you in midair with his slow projectiles.
Despite the obvious counterplay, don't use your ult exclusively to counter Makoa ult. He can simply wait for you to die to use his ult, and you can charge yours significantly faster than Makoa can charge his anyway.
