I find there's a pretty big difference if you are always casting. I previously had 11k MP as SCH as well and have around that 18k number now, but everything costs more at 70 too. I play as I did before and there's a massive change in the amount of MP I have unless I pop Lucid Dreaming. However, I do remember having MP problems in early Heavensward when I previously did not in A Realm Reborn, so it could be that again and will resolve itself as time passes.

Still, what reason was there to increase the cost of Adloquium? Did they just figure that because we had access to Lucid Dreaming, we shouldn't keep the same cost as before? Like, I get the Aetherflow change since we'd basically have infinite MP while comboed with Lucid Dreaming... but it's a bit of a puzzler to just up the cost of one of Scholar's main mechanics. Was it basically the only thing that got an MP increase in 4.0?
