Ive got invites to Farseer and Tod have been carefully collecting mats till Ive got the requirements hence my foray into combat as a means to fill upFair enough, to he honest weapons tend to be to be to taste anyway, so if it's working for you, I'd say carry on.
The thing to remember is that Nav beacon Anacondas could be fairly low level (I've seen them as low as 'competent'). The ones I've seen chasing me after incoming enemy alerts are rated as dangerous or higher. At these levels you're up against engineered opponents, so it may be worth looking at the Dweller for some efficient mods on those beams and a trip to Tod the blaster for overcharging the multicannons.
Unlocking those 2 will set you up for invites to the best shield generator and hull/armour engineers in the bubble, so certainly worth a try. You don't have to kill yourself maxing out g5 either. You'll notice a big improvement just going to g3 and those materials will be relatively easy to get hold of.
