Firstly, I missed the test server by 10 days... that is, I bought energy 10 days too soon. A bummer, but who cares, right?
Ok, here is my suggestion: OOO, what if we keep our current guns as "legacy" guns, and then we can get the new ones in addition? Hey, it's more energy that has to be purchased! It's a win-win, jack!
if you know how much the guns have been buffed in this update, you know that everyone will go for the new guns and screw the old ones. the movement while firing alone could be a thing to drive people off the new guns. it just won't work.
