How did you set up your experiment? How close to real matches do you consider it was?
Do you realize that pwerfer and wstukas projectiles land almost vertically meanwhile the allied variants have some horizontal velocity in it?
I cant really agree with the argument you bring in unless you really show a correct procedure according the game mechanics.
I agree with serrith about the wiping potential of rocket arty.
I would love to provide you the exact procedures if you could promise me that you will absolutely read every single word of it.
I was going to post our experiment detail in January. Still, after I reviewed my previous posts posted on this website, I realized most people wouldn't give a garden about reading the whole article. Most of them read only the conclusion part and then started to make comments without even knowing what had happened. And this is the reason I chose only to post a conclusion here because people won't read anything else anyway.
So if you really want to read it, I will be happy to rewrite the whole thing and send it to you via a Word Doc next Friday.
And for directly rebranding to your questions, yes, I have considered all of the side effects you mentioned and even beyond them. Rocket trajectory does not affect the time for them to land, it is, however, affecting their chances to be blocked by buildings. And Katy (and Colliape) is the only one that will be heavily by this factor.
