As for crit being largely overheal, the same goes for the cloak, but you neglect that - you assume it's 2.5% healing. Note that Malkorok is a really shitty fight for cloaks either way due to no overhealing (absorbs) and smart healing being distributed to the same targets), but I understand what you intend to relay with the example.
In the end, it probably will be an extremely minor HPS loss to not use the cloak, but that's to be expected - after all, it IS the healing "legendary".
Either way, with the way it works for disc, I'd much rather use the Yu'lon cloak for every single aspect of progress. You are downplaying the amount of damage it adds significantly, too - 2.1M on malkorok is pretty damn laughable, mine contributed 8.5M this reset. Likewise, I did 270K hps - even assuming the cloak "worked" and gave me 2.5% healing increase through the proc (assuming the 5% buff/.5% of it is outweighted by the crit), that's 5.4K hps traded for 23.5K dps. As the cloak is closer to a 1% healing increase in general, its just... Never worth it. It won't ever provide you with any life-saving healing. Heck, it's far worse in 10 mans than it is in 25 mans, because atleast on 25, the uncapped lvl 90 talents have a chance at giving you SOME overhealing when it procs.
