I do believe I posted this already - but here goes again...
Definition - partial action - PHB glossary
Definition - MEA - PHB glossary
read - apply logic; you get
Standard A = MEA + Partial A
However, if I thought I was right and you were wrong, that might be denial, depending on the circumstances. Unfortunately, I'm not saying I'm right. I'm only saying that you are incorrect.
I did forget to make the exeption in your case... but
1. Everyone except you IS in denial.
2. You yourself state that my logic strikes you as "wrong" - but cannot prove why. Good - that means think about it until you can explain it.
3. People are creatures of habit; Psych majors know this. Time to break some people of some bad habits. That is what those of us who are free thinking Philosophy majors do.
Well, you could define it as Partial+MEA/Move, but the game mechanics treat is as a single action, not two seperate actions.
Caliban, it is precicely because of the fact that the game treats it as one action that this whole thing WORKS:
Standard A = MEA + Partial A - given definition standard action
Standard A = MEA + MEA - given definition Double Move
Therefore -
MEA + Partial A = MEA + MEA - by substitution
Partial A = MEA - by elimination
I do the following -
Standard A = Partial A + Partial A - by substitution
as demostration for the "four spells in a round" w/haste bit. Omit it if you like.
You get stuck doing one of four things.
1. altering the definition of Double Move
2. altering the definition standard action
3. breaking the rule of substitutional logic
4. admitting they are the same - and responding accordingly.
One and two cannot be done without fundamentally changing the system. As I am not WotC - I can't do this.
Three leads to the impossibilities of "acting only on your turn" counter-intuitiveness and the static universe absurdities that follow.
Four - while possibly unpleasant in the fact that we must change our way of thinking, is a whole lot more palatable to the "suspension of disbelief" than three.
