I have a crit build and a double shot build, crits are nice but rare. Realistically you'll have 20% crit, armour and man of steel completely negate this. So this is 2 perks used for 1 in 10 shots at best, almost nil against a real target. Getting 2 shots off doubles your damage output every time and is more likely to succeed. Finesse and bg don't mix, anyone with 10 luck is pretty much invulnerable to you.
