I have a question for Codewalker or anyone else who may know:
Is there an ETA on when Teleport will be implemented into Paragon Chat?
No ETA. It is one of several powers that had the data necessary to make the icon appear gathered and added to the last update, but is commented out because it's not functional. Several things are missing that are needed for it, like instant position updates over XMPP, better synchronization of relative time between clients, handling of the power activation subcommand that specifies target coordinates, and teaching the ad-hoc 'powers' system that things other than toggles exist.
Teleport is by far my favorite Travel Power, I never really used it though because unlike my dad, I didn't know how to change the key binds and what not when I played CoH/CoV thus making it hard for me to effectively use Teleport, whereas my dad would just Shift-Click with no problem.
It's my favorite travel power as well. Nothing can touch its speed in the hands of a skilled user, especially on /energy blasters. I often wished we would someday also get a 'Combat Teleport' with a shorter range, faster animation, and no forced hover.
I never did like the shift-click bind, though. I dislike having to hold a key down, and you don't get the targeting reticle to warn you if it's an invalid destination or not where you're expecting.
Instead, I put it in the slot on my tray that I had bound to the 'Q' key. With my fingers normally resting on ESDF, a series of Q[click], Q[click] is quite convenient and just as fast as shift-clicking, with the added benefit that I can add a small gap in between if I want to see the destination and change it at the last moment.
