When you have many players that can solo +4/x8 any additional player is superfluous. There's nothing wrong in my mind to want to be able to solo like that. But having the character that can easily solo +4/8 participate in a team at less than 50 and still have 100% of their powers, including I-Powers (except for the 2nd and 3rd level shift), is beyond absurd and makes the rest of the team completely superfluous while the Uber-character isn't even breaking a sweat. Beyond that, it makes little logical or lore sense for one to have all those powers when specifically "powering down" to help, which is what the exemp system is supposed to represent.
