You guys are saying that the normal version is meant for weaker groups. You also say weaker groups shouldn't clean the instance so they shouldn't have acess to the normal version of the item. Clear your mind please xD.
That is precisely the opposite of what I am saying. The normal artefact is now again farmable for weaker groups while they improve their characters to a point where they can get the improved version.
Instance is harder now than it was before. B1 removed possibility to kite. Locatha not dying at 50% means many groups can't kill it, etc. I think if you really wanna make normal artefact to be used by weaker groups, then activate the npc without needing last boss so those people can still farm the simpler version of the artefact.
And in addition to this increase in difficulty came a new form of rewards. Again: You do not need to kill any bosses to get the first artefact. Only for the refined one.
