Sentry Turret, Sabotage and Homing Grenade (HG isn't as good as the other two). Sabotage easily deals with pesky Cerb Turrets and destroys Geth. Sentry with AP Ammo for Cerb Atlases, or Cryo, and Flamethrower destroys weaker enemies while I focus on bigger ones.
Yes I'm a newb, and I realise TurEng is actually pretty bad. I like it though.
He isn't, too many people are obsessed with having the highest DPS. I play the Saboteur in gold and he does well enough.
DPS really isn't that important. Sabotage a Praetorian's gun, they take 500 damage and don't fire. Same with a Scion most of the time they only get 2 shots which is a huge benefit to a team. My sentry soloed a Praetorian and 2 Scions in the match I just played. Bronze though, so it doesn't really matter.
You really can't be bothered to type an extra half a second's worth of letters?
Also, I've been playing the Saboteur a lot lately. His Armiger passives alone are a lot to brag about, coupled with the fact that Homing Grenades provide a very useful armor debuff. He's not half bad, I just wish he didn't have crap skills against most factions. --- "Limits, like fears, are often just an illusion."
