At the moment, in the realm of high end drones, there are this many:

Mining: 0
Radiation: 0
Laser: 0
Surgical: 0
Energy: Bule Mobile Blaster 4? Need more
Heat: Armada Inferno! yay

Support: Armada charge, Superior Protection, Bubble Drone, Advanced Command and Control Drone

Support has a sufficient amount, most people would agree. And engineers are a supporting class. But I really feel there should be more options for leveling and being useful (damage-wise) past lvl 800. It's quite hard to kill even the first level of UZ as a Drone Master 20 with Drone ops mastery augs, with anything other than Armada Infernos. Even if i'm doing it wrong, I think there should be more high end drones with more damage types

This game would really enjoy, in my opinion, many new items, they dont have to be too usefull or even used, just to interest people and make them try out new things and in a way .. er .. force them to remain in-game? No idea, something like that.
Like many,many new items that players will have to explore, and that are ... quite easy to get and not too powerfull.
Of course admins got enough on their hands atm ... I dont even see a use for the suggestion forum anymore it will be quite unusefull for severall weeks till admins are done with their things.
Not saying that the suggestion forum was ever usefull ... but anyway

I would say BFD are quite nice in both laser and Energy part.
You missed a whole damage type in there wich is Physical, Armada/ambush drone anyone?
iirc MMD has some decent mining damage even tho its T10.
alsoe does not the Blue Ada drone have a rad wep?

Yes but not the laser really for BFD. MMD doesn't have decent damage or usable elec regen
Blue Ada drone is tech 10 also and has about 200 range and under 200 dps

Mining: Hephaestus' Drone, Mzungu Mining Defender
Radiation: Bule Ada Drones (these are high end actually)
Laser: BFD, Armada Inferno
Surgical: Hephaestus' Drone, Armada Ambush Drone (awesome surgical damage)
Energy: BFD, Armada Ambush Drone (awesome energy damage)
Heat: Armada Inferno Drones

Support: Armada Charges, Superior Protection Drone, Bubble Drone, Adv CC Drone, Huge Forcefield Generator.

I think there are more than enough. High end does not have to mean T20.

t20 is the plateau of casual play though. it really should represent all elements of the game.
