Well, for Bind particularly, It's one of those maps where if u have a good setup, Like Optic, People struggle to get onto site let alone u needing to retake. (That's why Optic and SEN are so strong on it
For the jett pick, It's frankly quite useless on Bind apart from B site, and even so if tenz dies, There's little chance of that getting traded out, since the person is probably backsite, (Therefore he opened up literally 0 space and there was enough rotations to hold site anyway because rotations)
Optic hold 1 Elbow 1 somewhere like spawn or right side of site (From atk side) and 1 back and 2 a, possible 2 a 2 b and 1 spawn for rotations, and it's honestly quite simple, Bind is more of a gamesense map than a aim map, u need to play properly, aim can't just carry u imo.
Astra is overpowered on either side of Bind because of the suck, the possibility to just stop a push with a single piece of util is insane, With Viper there's insanely defensive walls u can use on A and good 1 ways on A, It sometimes makes A completely null and void if there's a good viper in the game (https://clips.twitch.tv/FrigidBeautifulBobaRaccAttack-jpA946BeIb6ZfXvN example of how overpowered viper can be on bind if u have a good viper)
With Raze she is so overpowered again because of the util, Bind is a map where u need to push after u get picks, if u have astra on 1 site and raze on the other u can completely hold up pushes until your entire team has rotated, that's why it's so defensive sided imo (Why u need to push just after u get picks is because if u don't u will get util stalled for like 5 centuries)
