Since hunter is unsustainable with 1-2% of players gaining 2m xp/hr with a useless spell I think it's safe to say treasure hunter is also unsustainable with 30mxp/hr. Is treasure hunter at 30m xp/hr worse for the game for all skills or hunter at max 2m xp/hr? Is treasure hunter causing the game to spiral out of control like hunter xp rates are?
Jagex can turn a blind eye to TH because it benefits them (gives them profit). Hunter wouldn't be touched if Crystalise came from micro-transactions. They only care about game integrity when it comes to content that players don't have to pay additional money for..
