So we get new artefacts and need to plus them all over again? I mean, its not that expensive, since its just some dailies but...
Maybe you need a +6 normal artefact to refine it? Would be the best solution for all
Or when you refine an artefact, it's level remains. So if you refine a a+6 artefact you get another +6, from +3 you get another +3 and so on...
