The overall problem is (imho) that monk is both a "pure" AND an "expert only" class and if you're expert enough to milk a monk, you are expert enough to do MUCH better with a multiclass, which leaves pure monk as a sad little trap for newbies.
Pure monk should work pretty well for newbies, but it doesn't. A big reason is late-bloomer syndrome in heroic -- far too much is delayed until cap when it should be L12 core at latest or somewhere in the tiers (profile in particular) so you can actually use it in heroic.
The MRR cap issue is (imho) a generic issue and should be removed for all armor. Cap removal won't change MRR on light builds by much (it's pretty hard to push past 100 and stay dps-focused). It will put cloth on par with Light, though, and it badly needs that.
BTW, throwers are an abomination before god (which is likely partly why I play them
).
