If you try this, I'd love to know the results, since right now I am stuck with finding a fun build with the Adept that I can't do better with the Sentinel.
Also, I'd probably recommend using Liara's Warp for your primer, so you don't need to wait for 2 cool downs for an explosion, and will be able to throw out Flare's every ~6 seconds as that is around how long Liara's is as well (or you could use her Singularity, even quicker) -- sounds pretty devastating!
Couple that with leveling up Liara's Squad Warp Ammo, could be an interesting and LOUD build.
Yeah Liara is a must. I'm actually trying this right now. I've started from after priority Citadel 2 so I have access to kaidan and Javik both. This build requires all squad members to be biotics. So I had a little dilemma about 3rd squadmate but I figured it out.
I tried them both and Kaidan seems better but lets take a look:
-He can tank thanks to damage reduction from both Reave and Barrier which is quite needed, Both liara and adept shepard are squishy.
-His passive provides largest amount of bonus power damage to squad mates, matched only by sentinel shepard. Seeing this squad is focused on powers its necessary
-He brings assault rifle to the squad
-Reave can be a good prime
-Most importantly he offers overload which is vital for this squad as it has nothing noticeable against shields.
- Cyroblast is not useless but it has limited use with this squad
Ignore cyroblast and max the rest
Javik:
-Dark channel is a good prime
-Pull is useless as shepard has it too and it has very little use in explosion focused squad.
-Slam has biotic explosion upgrade but does not penetrate shields or barriers.
-His grenades are good for exploding
-He brings assualt rifle.
Ignore pull, max the rest.
3 things make Kaidan better to take with this Shepard:
1. He is much tankier than Javik and this squad needs a tank
2. He has overload which is great for breaking shields and barriers alike.
3. He provides great power damage bonus to the squad and since this squad is based on dealing power damage its a must-have.
However if you don't have access to Kaidan, Javik is not that bad, he can replace Kaidan.
