So a speed tank glass cannon version of a raven. The potential for fun is there. Power level looks to be on part with artillery tornadoes. It lacks the tracking weakness so probably needs large weakness somewhere.
It would get more use as a PvP platform than station bashing from the high alpha. Paired with a set of target painters, it can take out tacklers with one volley. It may be hard to counter at range once that beast gets up to speed.
Nerf the base speed a bit and reduce the mid slots and you’d have something interesting without too overpowered.
The slot layout does fit better with the caldari theme, maybe one for caldari and one for min. Reverse the mid/low count for minmatar version.
