Given the proliferation of teleportation and transit options in the game, the tier 5 Teleportation power Long Range Teleport really has very little use.
I would suggest changing Long Range Teleport (and the Warshade version, Shadow Slip) into a Teleport To Ally ability.
Ally has to be in your Team or League and has to be in the same zone as you. Range would probably be the same as Recall Friend.
Animation could remain the same as the current Long Range Teleport animation.
The recharge could be the same as other powerful tier 5 pool powers, that is 10 minutes base.
I would love to see this ability added to the game.
