The most essential passive skill at early stage

Regardless of any classes/profile/skills, the most vital skill to invest is ....
The rank 5 ' In The Trenches ' under Combat fitness skill.
It significantly reduces the 8 second to 4 second waiting time before start regenerating shield

Wow that's the bomb-
The way things work for me personally, it happens that now I'm eager to get into the game and see how I chose to go on that. I do not recall, however, Combat Fitness was/has been my focus all along. Spirit'n guts!
Thank you Ho.Ly_MO.Ly_SexXY㊣

I like Energy Drain plus Tech > Team Support > rank 6 > Life Support.
Life Support basically makes you the team healer and Energy Drain restores shields immediately, ignoring any waiting period.
With Life Support you can use your tech power at nothing at all and still recover health.

In The Trenches is rank 6, only works for yourself.

After getting my feet wet with the systems I restarted as a Biotic to unlock Barrier then respec'ed into full Tech. Now I get to buy Barrier without wasting points on prerequisites in Biotics.
I pick up one gun skill eventually and that unlocks Combat Fitness at 9 points spent. But still basically go full tech.

Fitness and your weapon of choice are pretty much required, then do tech/solider/biotics or of course mix. the selection basically is the explorer build, which would fit seeing the game feels like it was based around that style.

Shock Trooper for Biotic Charge is good as well, reduce cooldown by 75% can pretty much spam it for unlimited shields. Combine it with annhilation Field for priming and Detonate with charge.

owh i never felt tired with the animation of Charge , it made me feel like superman or one punch man insta kick someone ass from distances like a , absolutely satisfying

i did tried Shock trooper, but ended up respec points for bastion, too hard to forgone the defence + damage boost, and i like the sense of danger, which i need to rely on maneuverability , cover, environment is best friend, therefore i find ' In The Trenches ' so helpful, and i would like to add that invest in passive skill of biotic ( containment , barrier , offensive biotic ) totally worth/ it
