Revival can be nice, but it's very niche. Compared to other throughput CD's it's very weak but it's instant which means if your team is struggling to top off the raid right before you know a big raid wide ability is about to hit it can literally save the raid, this happens pretty rarely though. The dispel part of the Revival get's very little use too, in fact the only time I can think of is the trash leading up to Will and LFR Tsulong when the whole raids stands in Nightmares.
Some tuning of Revival and Reworking of Zen Med would go a long way to allowing Monk healing to be reduced whilst not risking their raid spots but I am not full of confidence on this as it has been raised repeatedly throughout beta and ever since with no response or action from the devs.
Fortunately my mainspec is Brewmaster (which means I have gear for windwalker too) so I plan on staying as flexible as possible to make sure I am not left playing a weak spec.
