Some people don't like pop ups (I remember the discussion about reactions) but I would like a pop up (optional from the settings) before the dialog where in nice words (Shadowheart thinks you are too dumb to answer. The dialog is in need of a real hero, me, Wyll. or so) the companions offer their help and their stats are shown, then you can choose.
Sometimes (quite often) I also want to fail dialogs, so I would take the person with the least chances to succeed, as often there is sadly no "Attack Goblins." option in dialogs.
