It is annoying, I'll grant that. There are a few things you can to turn the tables though.
1. Make sure Report Crimes Against Me is Turned On, and park yourself in their field of fire. Not quite as useful in Haz RES or CNB's, but at least you're in their way.
2. Block them and re-enter the instance.
3. Carry at least 1 rack of Seeker Missiles for a Quick End.
4. Pull directly in front of their canopy and trigger chaff. It's supremely annoying.
5. Drop a heat sink right on their canopy. It's also supremely annoying and blinding.
6. Park. Yep, just sit there. Don't shoot at anything, wait for them to make the first move and steal their kills and then send a local message along the lines of "Was it good for you?"
