Suggestions from my guild:
If there is anyway to remove/ignore exit combats with stealth that would be wonderful, don't know if it's possible. I know you can manually remove them from combat logs and then upload them to torparse.
Percentage of time there is a armor debuff on target in group raids (again not sure if possible).
I am currently looking into this feature. I can't promise anything because SWTOR combat logs are notorious about abilities being out of order. I am not confident that I can count on the order of the enter stealth and exit combat events, which would be important in any solution to this problem.
