Since positioning your Drone in spots where it can't get shot is fixed,let's talk about further tweaking.

I did some Testing and my thoughts are the following:
That Antscreen/Blurr when the Drone gets hit should be toned down,it is nearly impossible to see anything if you get hit by something that is able to hold a weapon.
It is a good change that Droners can't solo everywhere while parking the Drone but to be viable and not share the same Fate as Melee users,they still need to see where they are shooting if they aren't healing up.

Raptor needs some sort of balancing,too.For a Drone with this TL/Req the Damageoutput is way too low.Maybe add some small second damagetype

Let's hear your thoughts about this and please keep it civil
