One of the biggest changes of the new season is the Frag Grenade nerf, where the devs have removed the ability to cook the grenades. So now, players will only be able to throw the Frag Grenade, but it will have a similar mechanic to the Stun grenade, where the fuse time decreases to 2 seconds after the first bounce.

This nerf allowed the devs to give Frag grenades to multiple new operators, therefore reducing the must-pick nature of certain operators.

Apart from that, the balancing changes include Mira Windows now being able to be countered by Ash and Kali’s primary gadgets. The bulletproof glass will be shattered if a Drilling Projectile explodes successfully after drilling into it.

On the other hand, Maestro has been given an extra Evil Eye and the active time has been increased to 6 seconds (from 5). However, the cooldown time has also been elongated to 6 seconds from 5.
