if deadlock is so good then lets have a quick rundown of their abilities.
Gravnet:
Looks like the worst thing ever. It is so situational and you can just hold down for 0.5 seconds to get rid of the crouching. Enemies only know if your in the net when you get rid of the net by holding down. Useless. The only time it can be good is if ur using it with a molly as a combo.
SonicSenser:
It's best ability which is actually good and can work well in combinations with trap plays but thats about it.
BarrierMesh:
Kinda bad as if you stop a heavy push they can just break the centre and done but it would be used to hold off spots which won't be contested often but even then its just a worst sage wall.
Ultiamte:
Easy to dodge but it is decent in 1v1's and 2v1's and 2v2's
Overall a C tier agent
