Looking really nice and I like the temporary buff level idea. You said about having a version that adds two stars temporarily? When exactly would that occur and depending on why it's there, would it tip the balance a bit?
If i read it correctly, he created 6 perks of his own using serverperks and you aren't using stock perks. He has "master perks" that grant buffs like reload and carry weight, and leaves the whole weapon perking thing to the weapon perks themselves.
I'll contact him when I next see him online and get him to reply to here just incase but other then that be a little more patient and don't expect much
This and rpg mod were among the most exciting conversions i've seen... Too bad...
