mk, i was incorrect... the kol GRG does have a first strike capability to do damage before shield mitigation is raised...
I just did some tests with some starbases, kodiaks, and carriers... and without pacts, but maxed armor and hp carriers survive with ~250 HP. Which is exactly what it should be using a 15% shield mitigation. even at maxxed everything -pacts all kodiaks died. WITH a tec/vasari alliance, however, THAT is when kodiaks just ever so barely survive with 27.5 HP w/o shield upgrades and 96 with shield upgrades.
In other words... A KOL with lv 3 GRG can now OHKO all 3 scouts, javelis, and all 3 seige frigs.
It would NOT kill a LRM, nor a seeker vessel with tier 1 upgrades, however. (and slightly upgraded siege frigs would also prolly be un-one-shot-able)
So... if you have a lv5 kol clearing millitia... and you are reaaally good at sniping ships without your other weapons firing first raising the shield mitigation... it might be quite worth while... but in an actual battle... you might be able to first strike an enemy capitalship for 892.5 damage. *shrug*
Oh, and if your using GRG to first strike... the -100 speed reduction is really useless, cause the enemy capital ship aint running.
