I find it interesting that no one seems to advise taking 6b on Biotic Focus for the extra movement speed. Because whenever movement speed comes up with other characters, everyone is in favor of more speed and getting hit less. I guess I'm asking someone to explain why shields are more important on the Cabal when she so easily gets to 1050 anyway.
Because other kits either have awesome power damage (or serious debuff) or weapons damage. She has neither. She has Turian Passives, which are good, but she can't instantly strip shields, she can't make her own biotic exposions and her own tech explosions come from ammo + PS which is slow and unreliable and not always feasable, because of range.
Her damage comes from her gun and Nighshade Blades, which are in limited capacity, only affect 3 targets, don't go trough cover and can't be used from cover. So basically you end up shooting your gun and spaming Focus for shields regen to stay alive to upkeep DPS. The other Focus evolution cause you to retreat too much.
With Biotic Shield you can eat swarmers, eat Banshee balls, time it right and ignore damage entirely.
