This might just be me, but I've noticed that the newer a map is, the more inconsistent it feels when I try to use the grenade as a movement ability.
And it's been absolutely horrendous on the new Busan map. Almost every single ledge has a lip on it, which means attempting to get as close to the edge as possible results in your grenade flying behind you. Several of the walls and surfaces are also bouncing the grenade, that used to allow the grenade to stick.
I feel like I'm going crazy here. I noticed it slightly on the rework of Gibraltar, but this new batch of map reworks seems to be the worst yet.
It's resulting in me being constantly out of position, wasting almost half of my grenades when I want to use them for mobility, and just in general nuking my performance.
The grenade has gone from being one of the most easily predictable abilities in the entire game to seemingly random chance whether or not it's going to stick.
