Team Teleport can be very useful, for Masterminds, Controllers (anyone with pets, really) and anyone with a team that can use it properly. There's nothing like the entire team engaging at EXACTLY the same time to tear a spawn apart.
That said, I think a great idea would be to expand all the existing power pools, to add a few new powers. The suggestion I had originally made was that each pool get one additional level 6 option and a level 30 option. My level 30 option for teleport was essentially your "Wayfare Teleport" which I called "Warp" I think. The extra level 6 option was called "Blink" but it was a short-ranged teleport with no casting time, a cooldown, and a small +defense buff.
Team Teleport is quite useful, TYVM.
As for zone teleport, where does it teleport you to? And if it's to just one specific spot, why bother with a power pick when you can just use a SG's teleporters, the BM/WW teleporters and the like?
Options for 4th Tier Teleport that are cooler and more useful than Team Teleport and also not that hard to balance.
1 - Zone Teleport - really, some of us have about umpteen of these as options anyway as temp powers, just a zone teleport power that lets you port to any zone you have all the explorer badges for.
2 - Wayfare Teleport - teleport to a selected wayfare point on the map, ie: trainers, vaults, stores, allies
3 - Banish - T-Foe that targets a foe and sends him fifty to a hundred feet away from you, no need to target, just throws him straight back
4 - Blink - Toggle +Defense
