If that's to knock down shields for priming via Pull, why not phasics instead? If you're up against an armored target which Pull will never be able to prime but Reave can (for some other biotic to detonate), wouldn't disruptor risk overwriting your own prime?
Disruptor Ammo/Overload/Whatever do not "overwrite" biotic primers. They STACK WITH them. Here is a simple experiment you can do with the Asari Adept:
1- Prime with Warp
2- Shoot Disruptor
3- Throw (detonates Disruptor)
4- Throw (detonates Warp)
Warp did not get "overwritten" by Disruptor. It was still there.
-------------------------------------------
Here is another example:
1- Prime with Dark Channel
2- Shoot with Disruptor
3- (teammate) Reave (detonates Dark Channel because it does not interact with Disruptor)
Dark Channel did not get "overwritten" by Disruptor. It was still there.
Teammates who cry about tech powers overwriting their biotic primers just need to adjust their playstyle accordingly. (Cast detonator twice if it interacts with tech, grats on your 2x explosions)
-------------------------------------------
It works the other way around, as well:
1- Prime with Incinerate
2- (teammate) Dark Channel
3- Overload (detonates Incinerate bcause it does not interact with Dark Channel)
Incinerate did not get "overwritten" by Dark Channel. It was still there.
