I think Tuyz’ Harbor on Pearl and Stax’s Harbor on Icebox were the two first effective Harbors ive seen in pro play (see: Dicey vs G2)
When everyone was first talking about Harbor on Pearl, it was with B-Site plants in mind. What I didnt realize—until Tuyz’s gameplay—is that Harbor is super duper effective on A as well. The slow wall clears out site nicely and the way his viper-style wall bends is perfect to block all the CT entrances.
And stax today…what else needs to be said? The way he used the armored smoke tech on 10-1 (2v4 site hold) was so awesome.
Go Harbor!
Edit: (Also Harbor’s ult on Icebox B seems really good)
