What am I seeing here? I have 2 points in the Safeguard skill which boosts my shield, and 1 point in the Hardened skill which boosts my health. The Centurion COM that I have equipped adds +3 points to Safeguard and +4 points to Hardened, making an even 5/5 for both.
I note my max shield and health before, put one more point in Safeguard and Hardened to push them to 6/5 each, and note my max shield and health after.
Conclusion: If the COM's skill-boosts couldn't push the skills over their natural limit, my max shield and health would not have gone up.
If you conduct the same test that I did, note that sometimes the max shield and health doesn't update in pause, which threw me off for a bit.
