It's not really about that, it's that it changes the entire dynamic for you to be there [i]before[/i] I charged. And you saying this [i]after[/i] I had already posted.
I know it's difficult to roleplay combat with multiple people, but that's like saying: Person A swings sword at Person B. Then a newcomer goes in and says, "No you can't because I was there the entire time and cast a chain spell on your wrists."

It kind of changes everything I said my character saw. Yes, I neglected to mention you in my most recent post, certainly my mistake, but I can't assume to change your characters actions and have him come in after my charge.

Not upset, and certainly not trying to be rude or harsh, but what I interpret you asking me is to change first post in the thread entirely, and thereby change all response posts after it.
