Wait and see for now
You can get into the tower again; Protector Reproach, from the Requiem Lant, will now damage monsters instead of healing them; There and Back Again gives you rewards, now; and, Second Age items will be cartable by some means. The cartable Second Ages are going to be called reformed Second Age something-or-others; there is speculation that this could mean all sorts of things, but it is best to wait and see for now. Still, it means you might want to reconsider dropping 10g on that perfect Second Age you just found at the AH.
