Is there any reason why the Corrupted weapons are locked behind the Xan Pack? There are no requirements to have the Xan pack to run the instance and the weapons are well below the performance of the Xan upgrades. Was this just done as a copy/paste of the Xan weapons with reduced damage? (The Corrupted Lord/Lady of Wisdom have no restrictions).
None of the other loot here seems to have any restrictions to a specific expansion pack other than SL.
They seem specced to be decent alternatives if you don't have the Xan pack.
