How do I get rid of it? It has no way to activate it so it just sits there. Any one else have this problem?
I have it as well. I consider it as some sort of trophy. Ha
Just one of the many things broken with TUs.
There is nothing you can do until they add the delete function.
Which should make it into the game in the next week to 18 months.
Otherwise known as “Soon”.
Classic dev move.
Is D3 secretly Valve? Their "soon"s seem to have the same definition…
Valve value their customers and make positive changes and good single player games you can play without an online requirement.
Teamups will be fixed as part of the DLC for Half-Life 3.
So it IS happening! 
I’ve never been stuck with a passive team-up before so pardon my ignorance… do those team-ups have any sort of cost to activate the (normally automatic) ability or do they say “Passive” only after you’ve selected them - and once in gameplay you realize that they can’t be used?
I’d rather them fix TU so that we can use passives throughout the round. Bullseye, Bullseye, Bullseye. Ha.
