I'd love the Avenger, but the biggest oversight is the lack of an Assault Gunboat!
I Agree, It was my favourite ship in Tie Fighter, medium mobility, good shields, well armed, not very quick. I wasn´t very good at anything, but it also wasn´t bad at anything.
This was my last take on Beam Weapons, some time ago.
Yes, even before the Tie Defender / E-Wing came out (hence Outmanouver)
Decoy Beam (1 p):
You can't be a target of a Target Lock action at range 3 or further.
Jammer Beam (2 p):
When defending at range 1, the attacker don't get the +1 attack bonus when attacking with primary weapons.
Tractor Beam (3 points)
When attacking a small base ship from outside it's firing arc, reduce the defender's agility value by 1 (to a minimum of 0).
I thought it would be best to keep them as simple as possible, so no additional tokens or other stuff that would make the game probably too complex.
