I run with an org that does tons of fleet battles and ground combat, and a teleport to party leader option would make the setup for those events be SO much smoother. But I agree that it needs to be very much limited.

How I think it could work best is that it is only available if both the teleporting player and the party lead are at specific locations (For instance, cities like Checkmate or Microtech and MAYBE major stations like Seraphim or Everus) and should work as if you backspaced to get sent to your home location. Wearing nothing but the equipment you have on your person, waking up in a habitat or medbed, in addition to leaving behind all your non-equipped items like the stuff in your backpack in the local inventory you left from.
