Ditch the alchemists. A 40 man army of transmutes is always going to be a burden. Just play the 1-2 team(s) you prefer and transfer those over to the realm you like. It's not like you are short on gold I presume or don't find ways to make gold apart from transmutations. And nothing prevents you to keep doing the transmutes on the old realm, and after a few weeks transfer one toon over stocked with the mats to your new realm.
