Unfortunately that picture of the Dunelizard has caused me to notice something about its shape that I cannot unsee.
Tell me.. you did not.. just post that.
Are you counting lasers or lasers and cannons? There's a very strong correlation between number of lasers and attack value. (.84, but I couldn't do a quadric correlation on my calculator)
I was actually looking at listed weaponry on the Wookieepedia, not "gun barrels". Lambda has 4. X-wing has 4. TIE Interceptor has 4. TIE Defender has 4 (& 2 Ion). B-Wing has a heavy laser cannon and autoblaster (plus 2 Ion cannons).
The XG-1 has 2. (& 2 ion).
There's absolutely no doubt whatsoever that - taking ordnance out of the equation - the XG-1 Assault Gunboat was lighter armed than the vast majority of the 3 attack dice ships in the X-Wing miniatures game.
With the aforementioned out-of-place and out-of role Kihraxz being a notable exception, of course.
We already have some ships and mechanics that only apply to Epic play, and more on the way.
We do, but this thread isn't about Epic scale ships in any way shape or form, so it's entirely irrelevant to the topic.
