@AsadNonari#1 sounds like something they should do, even a slightly faster drone deployment will make quick drone plays more viable.
With #2 I do not know how they're gonna handle the pathing, what if drone is deployed against a wall, you'll need to put it a lot of work to make it work properly.
#3 again is a matter of proper pathing, but grabbing nearby banner while interesting might be harmful when you instead wanted the drone to scout and give you wall hacks.
With #4 while I don't expect to see guns on the drone anytime soon, increasing the drone's juke (left/right) speed would be great.
