Who said ANYTHING about MP pool being a primary constraint?
I don't parsimony all of my nukes outside of abyssea, but I do parsimony a great deal of them.
Why do you Parsimony a great deal of them? Because your MP pool is your primary constraint. This is the only
reason one ever uses Parsimony, so if you say "I do Parsimony a great deal of them," you are acknowledging that your MP pool is your primary constraint.
I even gave a situation where time > MP...
If your nuke will kill with ebullience and won't with parsimony, you'll achieve the same result faster by using ebullience. This leads you to rest sooner if you need or move on to the next mob sooner.
If you are primarily using Parsimony, and decide to use Ebullience simply to kill a single target out of many faster, you might down that individual target a few seconds faster, but you are decreasing your overall MP efficiency, which over time leads to less kills over time and lowered efficiency. This is not
debatable. If you're in a situation where you're only killing a few mobs, or just one NM, you wouldn't be using Parsimony in the first place, and you wouldn't be using Ebullience, either; you would be using Alacrity.
You, once again, assumed something. Once again I say, read first.
I read what you wrote down to the letter and parsed it with some fierce logic. You're still wrong.
