Yeah, but you have to imagine cases; a BRD MRD BG will kill you in 2, sometimes 1 burst at around 10-15 hex. And if he doesent kill you in 1, taking stims will just postpone the inevitable. A SG sniper will outrange you and probably have higher %Crit, and the original build posted will shoot faster than you and have a +15% bonus on his crits, which will happen because you have neither bonehead nor man of steel.
I just think those extra HP is pointless with -15% dmg res. No, the original build is pretty good, but it is my opinion that 10 Luck is mandatory for a crit build.
Your build should take pyscho, have even tougher instead of sharpshooter, more crit instead of weapon handling, 2 int, 10 endurance, 10 agi, 6 PE, 2 str, and use plasma pistol/rifle.
