I recently tried out the Quarian Infiltrator in Mass Effect 3 multiplayer and turning the Geth against each other worked really, really well. But I observered that a few times my Sabotage power didn't seem to work on some enemies anymore.
What limits does the Sabotage power of the Quarian Infliltrator have? Why does it sometimes not work against synthetic enemies like the Geth?

I played around in a solo-multiplayer session a bit and found the reason why Sabotage seems to fail sometimes. The duration of Sabotage decreases significantly each time you apply it on the same enemy. So the first time you sabotage a specific enemy you get the full duration, but if the enemy survives that and you sabotage him again, the duration will be much shorter than the first time. It seems to be roughly halved each time you reapply sabotage.
After 4 times sabotage seems to lose any effect on that specific enemy, and this is not specific to Geth Primes or other superior enemies, you can observe that with any Geth trooper. The reason it seems to happen especially often with Geth Primes is that most other enemies just don't survive long enough so that you have to use sabotage that often on them.
