While the Justicar seems to be a soldier more than the others, as shown by her 6a racial, or her higher shields, i actually like to play her as an almost pure biotic. My biggest issue with the kit lies in shield: while the other biotics can somewhat deal with shields (powerful BEs, no shield penalty on some powers), she can't, which is very much a problem against Geth Prime or Atlases. Or even the speed she can deal with shielded mooks.
The answer to that is either: high sustained dps gun (Wraith, Piranha, Lancer...), a shield-stripping weapon (Reegar, Acolyte, Super soaker Adas is too ineffective) or Phasic Rounds.
Since i wanted to max out power damage, am quite at ease with not having any additional survivability, find the gameplay with Acolyte/Reegar quite limited, and not fun in the slightest, it could only be Phasic Rounds for me.
It took some time for me to find an effective setup, but i really like and am now very effective, whichever the faction on gold/plat, with this build.:
- Reave is at the core of the gameplay since stacked Reaves deal very high damage to barriers/armor and good enough on health
- BEs complement Reave's damage when possible
- Charged Arc Pistol does enough damage per shot not to be impacted too much by armor, which Reave and/or BEs will deal with swiftly anyway
- Arc Pistol+Phasic Rounds 3 manage shields well enough.
- 6a racial+ULM'd Falcon is for those Dragoon-heavy waves when they come in packs, or if have to protect a position by slowing the enemy (a hack for instance), and not penalize me too much with the additional weight
- Pull is circumstancial, but i'd rather have it, and at lv.4, than not
My only problem is that i've eaten through my formerly big stock of Power amps III/IV, which i used to shun, but took a liking to, after i wanted to spare my Cyclonics. Other than that the only thing with this build is that it requires to accept not having much shields.
