Remove it's active Teleport is a strange idea, why not keep it and just share CD with Town Portal Scroll & TP will not be comsumed? Many players complain they have to adapt new hotkey or set hotkey of Town Portal Scroll instead Boots of Travel when they play Tinker.

This also cause an abuse: At base, buy a Boots of Travel then TP out, then sell the Boots of Travel in the 3s.

Although TP base then use Boots of Travel out to regen HP&MP is bad, but this should not be totally cut off.
Keep this in Boots of Travel 2 should be better (not share CD with TP), because it need a lot of gold after all. And Boots of Travel 2 will become characteristic.
