In the end, everybody will get their gear. It's not as if raidsizes and groupsizes will suddenly increase with the same amount of items. If you take one monk in the group, someone else has to stay out. Regarding tokens they will add the monk to one of the new tokens and adjust the tokens droprate accordingly. So, what is the harm?
Additionally I am really relaxed about gear. I am happy, when I get something new, but I always know it will be replaced in a couple of weeks anyways. I am no loot-whore, so I don't have a problem. (And I have a druid as main character.)
