SONIC SENSOR (Q)
In my opinion, making it detect people that walk by but not stun them and only stun enemies if they make a sound around it, fixes the utility, resulting in a great map control agent.
BARRIER MESH (E)
The wall's health decreased by 200 damage, and by adding a recharge cooldown of 20 seconds after the first wall is down, you can use the wall again in the mid- to late round.
GRAVNET (C)
Add vulnerability to the nade and add a right click to place the nade. If you throw a nade, it produces two pulses, and placing it down will result in one pulse.
ANNIHILATION (X)
Decrease the damage required by 100–150, maybe, and add a key combo to tap multiple times from inside the cacoon to breakout.
