suggestion for Kalin artefact

Hi, few weeks ago you released a new Kalin artefact. 95% of players already crafted the very old one years ago and got xp on it. I would like to suggest to add an ingame item or item shop item that would add the possibility for those who wants to , to switch to the new one (without losing the already gained XP on it) , that is much more usefull (ressource reduction costs) than the old one that could only eventually slitghly benefit on bosses but that is in most of time totally useless.
