So to test my understanding, There is actual code that increases skill learning based on group size.... Does it really offset the amount of extra exp you get for having a larger group. So here is why I ask, logically, I would think that solo ranking ups the percentage that you would get in total for the simple fact that you spend more time at that level.(Lower Exp per Mob) But if the actuall code written makes this moot, well then.....

As for the Trolls, do I undertstand correctly that there is something unique to the Trolls and that skill learning goes up faster with them and then if the first premise in my reply is true, faster with them and a group?
