they should start making party play with specific set ups, where every class has its spot in it. like no more then 2whm or 1 brd, or say a party is 4 then there is free slots for other classes that you can add to the group only(so you end up with 8people in party but 4 are specific types that you can take with you or go with less). something to that extent where it makes everyone useful or at very least becomes that extra class that there isn't a reason not to have in a party less you don't mind less dps/buffs what have you. though people might not like being told they can't have 5blm's but just like the concept of capping all boss fights and endgame, this can also make it a little more challenging. not really thought it threw totally but i'm sure devs can figure out a way to keep every class useful. specifically the weaker dps, make them extra's for every party lol.
