@Infiltrators: Have not used these in a while, but they are FF immune and so I remember them being quite useful. On the Dark Matter thing, I randomly checked the wiki and none of the guard posts (that I checked) have dark matter immunity.
FF Immunity is powerful, but I will agree that the hull type changes on the guard posts have nerfed these, they used to have bonuses against pretty much every guard posts, now they don't and the DPS increase of the guard posts makes it harder for these to sneak in and pick them off underneath an FF.
@Teleport Raiders: These on the other hand I love. True, they can't 'raid' Data Centers or Raid Engines, but they murderize pretty much everything else, including a Wrath Lance.
I treat them more as 'Teleport Bombers' then 'Teleport Raiders'.
However, that was before the guard posts buff. Maybe now they don't have the punch needed any more to solo guard posts?
Having said that, posting a list of all the units and getting feedback on what peoples opinions of the various units are is probably worthwhile, I'm just not sure it's too soon after the guard post changes. Those changes are going to force us to re-think how we raid guardposts or specials near them.
