yes you can gain exp because you AND your npc were in a capped zone so you AND you npc were both level 30 so he gained the same exp as you did
but the other guy was NOT in a capped zone so his npc wouldnt get exp towards his level
Hmm, I disagree. Zones themselves aren't capped; rather, a level cap is a condition inflicted upon a character under certain circumstances. For instance, when first entering promyvions you are given a level cap due to your current status. But later in CoP storyline you can re-enter uncapped (or so I understand) and be in the same area next to people who are capped. So to say an "area is capped" is actually to say that your character is given a capped status.
That being said, I think your NPC is just being given a "capped status" under these conditions, just like what you would get if you entered a promyvion under certain conditions. Therefore, I see no difference between this and PC capping, and I conclude that your NPC should be gaining EXP.
