A lot of groups just want the boost to overall raid dps that trick and litany bring to the table, but an exceptional monk is always an asset to the party because they're capable of high individual dps and also have dragon kick. A top tier mnk with a nin and mch is a dangerous thing. Mantra tends to get overlooked, and personally i want a monk in the party just for mantra. I feel like mantra's utility is typically underrated.
