Help with field boss killer build

So I wonder what kind of build would do the best against field bosses.
I asked in various place and I’ve been told to go for qs3 fletcher3 or qs3 archer2 rogue musket, weighting the pros and cons I came up with this.

Things I worry about :
How tedious is it to keep hitting behind the boss, is rogue worth picking over archer2 ?
Is critical even viable against field boss of the same level range ?
I want enough CON to avoid being one shot, how detrimental is it for a dps archer considering it already has to put points into DEX for crit ?
Are physical dps even viable in late game considering the block penetration formula relying on SPR ?

Am I better off just rolling ele3 (again) and safely get my drops ?

Note : I want to do good against late game field boss, so using kneeling shot is not recommended outside of safety zone.

fletcher c1 isnt worth it.
rogue c1 ? hmmmm not so good either.
good skills for boss are multishot (archer) // Spiral Arrow (rangerc3) // magic arrow( fletcher c2)
then musketeer skills are also good for single target boss.
you will be surprised to know that 90% of the people i know use STR 4:1 DEX stat build. no SPR or CON.

I see, considering these I’ll probably go for QS3 fletcher2 musket because I think staying still while using multishot is risky, I really want running shot to boost musket damage and magic arrow looks safe and reliable.

Considering I won’t have archer2 25% crit I will have to pick around STR 3:1 DEX to make up for it ? well I guess I shall test this ingame and judge by myself, just really surprised they don’t pick CON.

Thanks for your inputs.
