yeah, the heavy machine gun is really strong ... damage against armor isn't that great but it is able to overload shields insanely fast. Eagle armed with three of those things can strip down shields of any cruiser-or-smaller target in just a few seconds (except Aurora, thats just because thing can outrun the Eagle). chewing through armor takes a while, but you have all the time you need, if enemy ship tries to raise shields the MGs will overload them again in no time
but the biggest troll weapon is deffinitely the tachyon lance (which should really be renamed to trololo lance). field Paragon armed with four of those, let it sit at rally point on the edge of the map, send a few of your fighters forward to spot targets and that thing can rip any fighter wing or frigate across half of battle map ... or across whole map if you hold one or two sensor arrays. if you field two such Paragons, there is no point for enemy to even try fighting ... any fighters or frigates simply won't even get to the middle of the map and even big targets won't fare much better ... the constant fire from the tachyon lances will either rip them to pieces, or force them to have shields up constantly and thus unable to use the speed bonus, meaning they will crawl across the map incredibly slowly giving even more time to the trololo lances to shoot at them, meaning the only difference is the tachyon lances will rip them to pieces a little later (after overloading the shields first). the only thing thats missing is the Trololo song playing in the background
