Pretty simple really: Trinity isn't getting many of the kills, its all of your team mates that are, thus you are getting the affinity split 25/75 between your frame and weapons respectively. Whereas with the Mirage, you are getting kills with your abilities and probably your primary weapon, and the rules above say that affinity will go to your frame (if abilities get kills) or frame and the weapon that killed the enemies split 50/50.

Therefore your low ranked secondary and melee aren't getting any of the affinity... which is why it seems like Trinity lets you level faster.
