I don't get why people can't see AP like this: Weapon upgrade
Example: You were in Highmaul, got a weapon from a boss. Then you do BRF 2 months later, get a weapon wich is a lets say 6.5% upgrade.
Same thing with artifact weapons and AP-grind, its just a more predictable upgrade to get.
To upgrade a weapon on how much you want/feel/have time for, isn't it awesome? Instead of hoping for that one out of 7 bosses wich got the weapon-upgrade you need, wich you share with 4 other players?
