I've completed the MA job series that provides +3 ac/ab vs outsiders, etc. On my toon's charsheet it shows an extra set of ab progression 'vs outsiders'. When the toon was a lowbie, and had only completed the first job, it received +1 ab vs outsiders, but wielded a +2 weapon. The charsheet reported +12/+7 and then +11/+6 vs outsiders. Now I have a bitter hatchet +4 and have completed the job series for the full +3 ac/ab. The charsheet is now +37/32/27/22 and +36/31/26/21 vs outsiders.
It looks to be reporting correctly, but also tends to give you the impression that your ab/ac vs ousiders is actually LOWER due to the jobs. Is this another one of those things where the engine just chooses the higher of the values? Having it stack would be awesome
As far as the combat log, I haven't had the occasion to remember to check while fighting an outsider, just hoping someone with MA experience or a dev might know the answer off the top of their head...
