Hmm, I've never overhealed MP with aether charges, to be honest. I do adloq, but only on big hits and shield worthy hits such as people entering towers twice, allagan field, or offtank dreadnought, and tanks that stomp on more than one mine but other than that it's pretty much brought me from 3.8~ to 4.8k, and I do keep tabs on the WHM's MP and if I see him get low I pushed myself a bit more, probably allowing me to get to 2.8~3.5k MP pre tower 6 but so far it's worked out pretty well. I just don't think stacking crit helps you THAT much, and consistency on the other hand (a good mix of piety/mnd/vit even) has helped me more than crit has.

But you get that awesome fuzzy feeling when an adloq does crit, though..
