Only reason I have stuck with that 268 lone star holster is it's the best I have (all 720 plus stats with 563 armour). I can happily sacrifice 10% damage to elites with a sentry holster if it means I get far better firearms, stamina and electronics as the other gear more than makes up for it.
Once decent roll 268 holsters start coming in then it will be replaced.
Love having 67% EDR though while still having decent, crtit damage, armour damage, health on kill, headshot damage and having plenty of ammo to play with.
I like to go for a more rounded build.
The focused talent I would normally roll into something else but I couldn't use the first talent as it required very high electronics so I rolled that out instead to one I could use. Can't remember the talent but it's the one that give 14% extra damage from 40m I think.
Would like to roll that to ferocious or destructive but 3 rolls and it hasn't showed yet.
Don't mind the focus talent to much because if I pulse I gain similar damage back anyway so it works out ok.
