Favorite Geth Engy

I use lore/roleplay Toaster Geth Engie:

Build

You may use him without fitness and put the points on Flamer

A Geth Sniper Engineer

If you are low on Cyclonics, swap the Turret to Fitness. Ammo is faction dependent.

No, I use it like this because I like sniping and after 880 hours I still haven't unlocked the Javelin...

I use him with the phaeston because I don't have the Harrier yet. The extra rof from Hunter mode lets you put incendiary effects on quickly for fire explosions. Then I go for the geth plasma shotgun to stagger melee enemies, such as Dragoons. Then I go for full shield restoration on the geth turret.

Overload keeps them in place. 

I hate indra's big ass sparks when shooting. Blocks the whole goddamn target. 

4/6/6/6/4 is my build, I want HM and passives maxed for damage. He's squishy though so for platinum bring high level cyclonics.

You could go for lower Points in fitness and more points into dmg on the turrets for messing around on Gold, but then again who want to do that?

No, don't give up, you can. Just don't scope too early.
1 Make it stop (throw turret, overload)
2 aim without scoping
3 scope and sharpen up and shoot

There ... you hit the Mako, see?

Split 4/4 between turret and fitness. Talon, AP ammo. Aim for the heads. The rest should be straightforward.

I would say this build i roll with its fairly unusual but it works great, i have very little trouble on gold.

Build

Geth SMG is great for shield/barrier stripping, incendiary ammo and turret with flamer to be able to do a lot of fire explosions for those pesky Armour units (Armour stripping is main problem with this kit tho), mooks with health are easily taken out since geth SMG can set few of them for explosion and chain overload hits 2 of them so anything in area gets burned, so good crowd control. Rest of the turret is for shield regen just in case of pesky objectives like hacks. Fitness at 4 just because i hate being too squishy specially with the hunter mode. 

Also instead of Geth SMG it works well with sniper rifles like valiant.

I actually do like the Indra with accuracy and ROF bonuses.  Also use it as a long-range backup weapon for my Talon QuarMark.

Really good kit with the wraith. Use the overload to reload hide. He is an absolute fucking monster. Csmg is also good on him with the rof bonus. If you just like popping domes though, saber with drill rounds is also therapeutic fun.
