When a regiment camps in unofficial matches for an hour, making the opposite regiment just charge across map without using any tactics just out of how silly it is, then that does not confirm that they are a league 1 regiment, that just confirms that league 1 regiments don't like to have their time wasted in unofficial matches.
Just let them prove themselves in league 2, then advance up. Just like how NWL was created to be. End of story ^
