http://social.biowar.../index/10618184 taking cryo rounds instead of armore pen rounds for your turret works just as well. its more for cc then for dmg to boss type enemies, however.
striker/falcon with disruptor rounds is amazing for this girl, it will set off area fire/cryo explosions.
the turret's flamethrower allows u to set off fire explosions.
i personally run with 6/6/6/5/3 i carry a striker and a geth smg with bigger clip and light weight materials
the difference i do is area cryo and incinerate, my reasoning behind this is that i completely control any group of mobs, outside of boss type enemies. this wont kill as fast as a batarian soldier, but where he is forced into cqc, shes got great range cc.
yes, to be used effectivly she is reliant on specific weapons, but if u think about it, so are all the classes, infils on snipers/shotguns (or the gi with the geth smg), strong caster types are reliant on pistols or another weapon with a low weight. so to say that u are forced to use these guns, is fine, ur forced to use specific weapon types for any class.
shes a fun character to play with, when i pug and use her, im 9/10 on the top of the board or maybe #2.
with my normal gold group, im toward the bottom, but what i bring to the table puts me at the top in my teamates minds. shes a great change of pace from the normal type classes and instead of focusing on making kills as fast as u can, ur role is to control any and every mob that advances into your line of sight.
last night, i dusted her off after not playing her for at least a week or two, and we were playing gold reapers on dagger, the only mobs that made it inside the hub were boss type enemies, and most of the brutes died on thier way in, the cryo blast on banshees + biotic explosions made them die within seconds, and we had few deaths (3 maybe 4), b/c we had to leave as a group for objectives, due to no infil in the group.
her turret requires u to keep throwing it, due to its complete lack of health/shields, but thats fine, in the time u have it down as a group of enemies comes at u, with the dmg increase of area cryo blast on the group, the whole group is nearly dead.
every game ive played against reapers (specifically yes) while using this girl, i cant even count the times its made brutes and banshees just stare at the turret and do nothing while it flames them to death.
shes the true cc'er with a great bonus of cryo blast to increase all incoming dmg to the target, shes versatile and does very effective dmg even though shes focused on cc. setting off her cryo blasts, fire explosions, and the occasional tech burst are fairly e z, and just happen naturally during game play, u dont have to really think about it, or train urself to cast and fire in a methodically and relatively boring method (ie the human engineer, a great all around character that we've all come to love)
