2x Improved Debilitators (may downgrade to Advanced to save energy)
1x Sidewinder Missile (ultimately worthless, but fun to play with nonetheless)
2x THOR's HAMMERS
1x Advanced Debilitator turret (nice on an Avenger or a Guardian, since it's turret is fully functional - 360 degrees)
Sunslayer Torpedoes (I like them)
Guardian
2x Improved Debilitators (I'm a shieldbuster whore, because for some reason I cannot kill anything without them, which is strange considering as I'm a pretty decent pilot)
3x GUARDIAN (I don't like the tracers, and I have problems taking down hull with these guns)
1x Advanced Debilitator turret
I wish the Avenger and the Guardian had six gunports, but I guess it technically does if you count the fully-functional turret. An 800m shieldbuster turret? Can't go wrong.
And yes, I do use gunpairs.. I'll switch off shieldbusters when fighting capitol ships and so on. I tried the following configuration earlier with pretty good results;
With this setup, I was able to down a GB's shield by 50% in one run before my power drained out. Not bad really, but you see since the Guardian only supports five guns, I can only mount the ARCHANGEL on the left or right side of the ship without separating my gun pairing. This sucks because it means that ARCHANGEL is somewhat limited only being able to fire from the left or right side of the ship. I can't put it in the center like I would want, sadly. I suppose I'll have to cope..
