We're at wave 7 and going strong in list diversity and choices for how to upgrade your squads. Ships like the Ywing and the Hwk gained a great boost from the TLT, giving two reliable damage at range 2-3. It's a hefty 6 points on your squad, but well worth it.
However, since being implemented the TLT has taken priority in lists as a mounted turret. I have not once seen the blaster turret in a list since the TLT was an option. Why is this?
Well, I ran a list that maximized on the blaster turret last wave and so I feel I am close town expert on why:
It costs a focus. This is hard for many ships to fire off modified, luckily the Argomech helps for this problem with the scum Ywing but not the rebel one. Most damaging of this set back however is a niche, Carnor Jax. I lost painfully to a list with Carnor, because I couldn't even shoot. I understand that this is "a bad match up" but it's in my belief that certain lists should have weak points but not one ship that's it's ability makes the list completely useless.
My proposal? errata the card to require a focus but not to spend it. It's a simple change that allows the card to not be crippled by Carnor, get possible play from rebel Ywings and not broken in terms of the card. For 4 points, it's 3 attack dice and locked at range 1-2, the Blaster Turret isn't better than the Mangler for the same point cost. It also keeps the turret difficult to use again Carnor (not being able to re-focus if spent) and if you tend to bump (which we all do from time to time)
I love HWKs and Ywings, and I feel they could do with another viable option for list diversity.
