I like this except I think players should be able to determine whether they want to pay another player a fee of under 400k pkp for inferno services. As this adds another dimension to the game, thus creating trusted players that can do tasks' at a cost to other players. Ex. completing certain achievements etc..
Or you could skimp ikov and do the infernal and max infernal where the regular infernal is just killing the final boss for it, and completing the entire waves gives you the option to attach it to a 1500 cape for increased stats.
