But why only ToO?

Prison is no place for second chances. ...or something.

But why only ToO?

Probably because time is such a factor. Being down a man even for a round or two could end up costing you a match while your teammate reconnects. And maybe this would prevent you from 'quitting' and losing automatically when you were in reality just booted to orbit?

What the others said, and also, starting with just one activity is probably a good way of testing it and how effective it is?

For now, Connection Recovery is limited to the new Trials of Osiris event. We know that disconnections are going to be especially frustrating in Trials, so it seems like a good place to start. Once we have a better feel for how it's going to perform in the real world, we plan to add it to almost all activities - if all goes well.
