Also i don't get why people keep saying that a HWK or even turret spam list are intendedly bad because this should not work because {insert weird fluff reason here}. But every other spam list is okay to them.
Don't know that anyone is saying it for fluff reasons. Myself and others have said it wouldn't work because of pure game mechanic reasons.
In order to effectively use the blaster cannon you need 2 focus, or at least a focus and TL. Both are difficult to come by unless you have a way of passing off focus or TL's.
The Blaster Cannon itself is nice, but is not by any means better then the primary weapon on say a X-Wing, in fact it's a bit worse. Sure it has 360 degree arc, but it also only has a range of 1-2 and loses the extra die at range 1.
Take the somewhat limited effectiveness of the BC and add in the need for 2 actions to make it on par with most other weapons and you have something that just isn't that good. Not good enough to base a list on.
Now the HWK itself, is intended to be a support ship, the stats, abilities, ect... Were all set towards this role. It was intended to be the Rebel support ship, like the Lambada shuttle is the Imp's support ship. Sure they could of made the HWK more of a front line fighter if they wanted too. But that would of meant finding a different ship to release as the Reb's support option.
