If they unlocked the hard or elite for that specific character that is a tr it would be fine. Vip gets it across the board and can do elite runs with a 28pt char to grind out tp quickly, where as the person tring would only gain the tp on that one character per life unless they ran it with other characters on n/h first. Im not seeing the issue. They can also join parties for elite runs already without expending anything. The difference is they have to have a vip opener which isnt that hard to find.
Im ok as long as it is a per tr basis.
