Share TSM Data between accounts
At the very least, it would be great to be able to share custom pricing information and settings between different accounts, as maintaining them is really difficult. (My posting toons are on different bnet account to my crafting toons).
Following on from this, would be useful to be able to share / synchronise operations more generally between accounts.
ItemTracker data and professions can already be synced. Beyond that, you’ll have to ask for Blizzard to increase the bandwidth limits before anything else is even remotely feasible.
