adapt to other players gameplay or not?

ok....supose there is a team, 3 players use blades, 1 use guns, and the gun user kill the criatures before the others can hit something, the 3 players tell to the gun user to use blades so the others can gain exp.
does the gun user have to adapt to other fighting stile just because he is better?

nope, no one has to do anything because it's an MMO and you can do pretty much what the hell you want (even if it is unfair sometimes).
