I really think the "transport request to objective" capability needs to be removed.
It really breaks immersion and just seems ridiculous that you can bypass enormous sections of the map instantly to magically appear behind the enemy. And you can then spawn other people behind you if you're wearing a radio backpack or you're a group leader. Its a bit silly, IMHO.
I think transporting to your group leader (within radio range and not wearing a radio backpack) is probably OK, considering the intent with that is to try to keep players together. IF there was no "transport request to objective" used, then at least they had to physically get there somehow.
