I did put missiles on it, for those times when it seems appropriate. I don't like using them in settlements, though. It feels cheesy and unsatisfying (to me). I'll do it if I just can't manage any other way, but I'm trying to learn to be better on foot
Speaking of which, I did get a chance to try out my newly upgraded shotgun (Grade 4 now). The stats say it has a range of 7m, so you gotta be pretty much point blank with this thing.
If I do it right, I can run up behind a guard and blast 'em. One shot is all it takes for some NPCs, even with their shields up (this was in a Threat 3 environment, so not very high level). 2 shots if the first one doesn't quite do it. Then I run off and circle around until I see another chance.
The NPCs are pretty smart, but it is possible to confuse them a bit by running off and having them lose sight of you -- then they will go into a search pattern and often separate. Then it's ninja-time again, lol.
It's not the most elegant fighting style, but it sort of makes up for my inadequacies (slow reaction, bad aim). When you're 3 meters away, with a shotgun, aim is less of an issue
Plus I get to scan them for bounties afterwards, which I cannot do if I kill them from a vehicle (they despawn when you exit your ship or SRV after killing them that way).
I haven't played yet today -- we'll see if the fixes fixed anything. Based on the patch notes, I'm thinking they still have a long, long way to go. The 'Road Map' tomorrow will be very revealing.
