It just struck me that I don't actually know the weapon arc of the Prometheus MkII, nor have I had the opportunity to get one, so I have no idea about how the ship weapon arcs go. There is no no real reason to deliberaly seek to fight Pather fleets and so it's like a black box of knowledge. From the sounds of it, nobody else had the opportunity to use it either. Unlike Atlas MkII, it is not readily available to buy or recover. I can't seem to find blueprints for it. It's moderately fast for a Capital. It's got two fighter wings, which always seem to be trash fighters under pathers, and it's like the Legion in that it is built to be exploited from behind. For all we know, it could be drastically under or over pointed.
Doom is good, both as a player and an AI ship. I've never had a problem with its cursor. There's only 2 Turrets and if they need to be constantly firing, just put them on auto fire. If they are "strike" weapons like phase lance or Heavy Blaster, just let go of shift when you are using mines. Being able to deploy mines when phased is so ridiculously powerful. Using mines is fast and as a phase ship you have plenty of time to decide when to fire.
