Disclaimer: I do not have the new Tau 'dex, so I am making a few assumptions based on a quick read-through.
Does the Skyray have a place in the Tau army? It's competing for a space vs. the Hammerhead.
Pros:
Up to 6 shots if it stays still. (Exhausts entire payload) - Splits fire at S8 at +5 points
Armoured move and fire markerlights
Cons:
6 shot payload limit
Expensive.
I am toying with the idea of using it as a Hammerhead replacement vehicle - as it is slightly cheaper than a rail-head. With a pathfinder team, going before it, it can fire off up to its entire payload at that offending enemy tank, with the ability to get flanking side shots. If it goes next, it can markerlight for something else - such as the mandatory devilfish (x2 seekers?). I'm not sure why anyone would take gun-drones unless they can detatch and count as a scoring unit (I forget if drones can score).
Am I correct in this assessment as to how the tank is to be used? i.e. As a sneakier version of the Hammerhead - Fire/Forget and then use as a scoring vehicle / LOS blocker (w/ landing gear)?
