Recall, yes 100% I think we ALL agree on this, cast time should be faster as well like 1s.
Tactical teleport, very yes, but it should have a base range of 60 or 80ft and no rech, something low like 2 end per cast, jaunt animation, .5s activation time.
Long range teleport is basically the travel, and should be the 3rd option tier 1, or should work like the mission transporter where it teleports your whole team, only you select the destination, and be the tier 3 5th power.
Teleport assault, should be the 4th power, tier 2. And instead should be "teleport punch" a snipe that works just like snipe powers and basically opens a mini portal that you do a quick punch through. Like the Spot on Spider-Man or Blinque.
Group teleport should be the 5th power tier 3 and provide a few second pbaoe confuse of the same 30 foot radius as enemies would be confused as to where everyone went. Rech time would be around 30 seconds. Or it should be the 3rd or 4th power without the confuse.
Edit: Or better yet, Group TP should be like "assemble the team" with something like a 30s recharge. So for MMs even, it would still bring the pets to where you are, but doesn't really need to take them/team with you. It should not be a power that is designed specifically around MMs, which honestly none of them need it anyway, and they could also just combat tp into a mob and then group tp (1s animation) to follow. This way we have that recall team, for so many support sets with buffs to gather the team up to cast them, or to recall the whole team to your location after long range teleport etc. This would be much better for more use across all ATs and playstyles. It could still have the 3s confuse too in a 30ft radius. For the MMs too, it could actually even work like incandescence, where it would tp you to the location, and then automatically recall the entire team after you pop out. That way with a few second confuse, you can go into the mob, (or not) and safely team the rest of the team from any range to your location after you get there. The confuse would be mag 4 to safely give you a couple seconds for the allies/pets to get to your location to share aggro when the confuse wears off. This should be the 4th power, tier 2, and then put long range teleport at the 5th power tier 3.
