The increasing gap between players and bosses.

If we are talking about lowering the gap between funded and unfunded in the context that the unfunded can be in parties. Why not add party only skills. As in you need a hero +paladin to uses this super uber-damage move. or have like a skill that reads out " if you have 6 party members increase your Matt & att buy 300 or +10% resistance for every party member" or something ridiculous like that. It promotes partying a lot of people and creates an atmosphere in which unfunded can take down harder tier bosses because they gain damage or class survivability they need to survive. As unfunded players dont care about being stronger than others but simply being able to complete the task.
