Levels of damage control:
- Spend Action (which may be free) to turn face-up card down.
- Just turn a face-up card down. (Chewie Falcon-D)
- Discard damage card. (R5-D8)
- Never let damage card have an effect and discard immediately. (AI, Determination, others)
There may not be anything that uses level 1 damage control although that could be used to trigger either PtL or EI. The issue becomes is how great is the need for something that does that? I'd say 0 points and eating any upgrade slot is more than enough cost with crew or modification slots being the step behind the astromech slots if preference. If it's a free action to use with a damage card it's hard to justify if it's just one card per round when you are unstressed; I don't care about your timing but it should be better than that.
If you charged 1 point for this upgrade it should ALWAYS work against any card that an Action could turn face-down. I'll even say it should work immediately after getting the damage card. Even with this it may be over priced and justifying that cost may require moving it up to DC level 2 in some form.
