Red Mage needs to Dispel *BEFORE* monks engage. This is the most common problem, and the most annoying. Red mages tend to really want to cast silence first and dispel later, after all monks have been paralyzed. This slows down everything, whm brd and rdm now need to cast a lot of paralynas instead of resting mp, singing, etc. Fight lasts much longer and mob spells will go uninterrupted.
Sure, bard pulls with finale, but often mobs recast ice spikes as soon as finale hits them, and recast on finale is really long. as soon as there's a mage mob incoming, RDM needs to dispel right away (before it's engaged, and before silence), and silence right after dispel. Not the other way around.
