Nothing more than a Barden (Riot please look into)

Just a note for Riot. I believe magical journey should be Both sided where you can use it on one wall and someone on the other side would be able to use it. it seems abit too pointless right now. another thing that could be expirimented on is that he can keep it out as long as he wants but at the cost of mana. think of it like the Thresh Lantern initiation. Bard opens a portal and the Jungler or Roamer uses it in order to come into lane. bard then will be able to immediately close the passage still allowing the jungler to finish his passage but not allowing others. i believe that this would make the game quite interesting and make Bards E more efficient. right now it just seems very unuseful in more than half of its occasions. please read dis Riot and tell me what you think
