Its been that long since i played the sentinel, that i've forgotten she was there, quite a versatile character, but on the build i used when i levelled her up, i had 1 point in backlash only. Pretty sure i just grabbed a build from youtube for this one, but the build i was using was
Backlash: 1
Throw: 1/2/3/4a/5b/6b
E.Drain: 1/2/3/4b/5a/6a
Off.biotics: 1/2/3/4b/5b/6b
Tech armor: 1/2/3/4a/5a/6a
as i said it was a guide i pulled from youtube, and its likely been updated now but what i will say is that i use backlash fully upgraded on my asari duelist and i know on that, its not just a lifesaver, but it is excellent cover for those situations where devices need disabling and you are just covering someone who is grabbing the objective so they don't get disrupted and has to start over.
Hopefully someone who plays the sentinel(asari) can confirm their build if they play on gold a lot, but i have to tell you i didn't start playing golds really until much later on, i was mostly on silvers.. i think 1.09 taught me that with so many cards now in the loot pool i had to go up to gold to stand a chance of maxing anything in good time.
