Let me preface this by saying that I did not delete a character and lose my items. I saw the warning and heeded the advice of "put these items in your bank".
That is where my suggestion comes from.
If we only get these items once, they (the maps) should not be bind on pickup. Bind on account would have been fine, but as is I cannot place them in a bank... making the advice posted at the top of this forum a bit misleading.
With the plethora of items in this game... my inventory space runs low rather quickly... having the maps bundles, along with the maps themselves, tethered to my one character is a pain in the arse.
I did not see a "suggestion" forum...so I placed this here. I may have missed it though because the forum structure here is not the best.
