I would like to have the Automaton Queen out for longer. Square won't allow us to have them out in cities like pets which is fine, in order to keep the amount of spawned entities/players to a minimum (plus the size the AQs take up) and reduce GPU/CPU strain. But having them out for 20 seconds in battle, even through repeated use, is barely enough to warrant creating such a detailed thing in the first place. After the initial activation, you should be able to keep performing the necessary weaponskills to keep them running and top up the charge, but have it cap out at perhaps 45 seconds via 'overheating' and shutting down (performing it's finishing skill still). And yes this 45 second timer would need to replace the original 20, not be something you get as an upgrade via a trait at level 90 and can enjoy in a grand total of 5 dungeons or something, when synced.

As far as new skills go, perhaps Machinist could get a 'snipe' skill. A one-shot of maybe 400 potency, but it has a range of 60y and there's a 'cast' timer of 6 seconds (any attack on you will interrupt). It requires you target an enemy in the normal manner. The recast can be 3 minutes, I don't mind. I just think we need to think outside the 30y box with attack ranges.
