My canon Inquisitor (nightmare) I play as a Hunter, i.e. Shotgun Infiltrator, if that means anything to you in Mass Effect terms.
Only Leaping Shot and Strafing Shots from the Archery tree, the rest equally distributed on Sabotage and Artificer.
I use Hook & Tackle, Spike Trap, Leaping Shot, Throwing Knives; in that order, and then just repeat. With the Artificer's "Opportunity Knocks" Passive (Every critical hit by anyone in the party reduces all your cooldowns. Yes, I know.) one Leaping Shot will recharge all your cooldowns, so you basically nullify them. Drop a Toxic Cloud here & there in enemy mobs so they don't forget you.
Stay in enemies backs to make use of Flanking Damage, and you're basically a DW rogue, except with a bow. Just an alternative to the eternal "stays outside of actions and spams ranged destruction skills". (I wanted to upload a video of that once, but it seemed pretentious. I just usually can't explain it very well.) It's a very busy style, but the damage is insane & your character seems about mine's age, so he can manage 
I played ME Insanity as Infiltrator too!
, and my style was similar to the one you mention (mostly in ME3 though), instead to do what the "experts" recommend, I rarely was too long in cover, moving around the battlefield, and I used 3 weapons (a "mortal sin" according to the "experts"), an assault rifle for most situations that I switched to the sniper rifle when I could, then a shotgun that I used to blow the head of unsuspected foes after popping out of stealth.
The issue that I'm having with Bows is not with the weapon per se, but the awful AI behavior of the melee DPS in general (in DAI happens, but is not the only game where I see this). My team was Cassandra (tank), Solas (support, barriers, rez), Iron Bull (melee DPS, two-handed, some talents that created guard), and my Inquisitor (range).
Even with Iron Bull generating Guard and with reasonably good gear, I never would have imagined he being so squishy! I spent more time keeping him up than actually fighting the boss (envy demon) in the last battle of "Champions of the Just" and don't make me start with Cole, that ate dust after one or two seconds into the fight!
When I play DW daggers, I usually play a "hit and run" style allowing Cassandra to pick up stuff and vanishing when things get too busy, and I position my character behind the boss minimizing the damage received, something that the AI doesn't seem to grasp with Iron Bull
