People do not need to change sides to spy. Some do, but the biggest offenders are those with multiple accounts, those who have the login/PW of their friends, and those who already have moles on the other side willing to PM details. This is nothing new and it happens everyday. Some even only have their squad comms on Skype or the like so that there are no witnesses to their multiple account shenanigans. Again, this happens every day and in more than one arena.
If it takes a squad three days to get organized that is SIX total cycles they could have had chances to all get on the same side and didn't. If that's the case that squad needs to get it's kraap together.
For those citing that "the fight gets stale", or that they can't find a fight they must be in the WWI arena or the Early War Arena at 4 AM Dallas time because there is a fight anywhere in LW that you go and start one.
A few days ago I was rook and the bish and knights were gang-banging them with no fight on their front. I went knights and took a gv to a bish base and started a fight. It wasn't 45 minutes and the whole knight-bishop front was full of gv fights and air radar bars. That means anyone can start a fight so that's no excuse.
The 12 hour rule forces sidehoppers to think strategically. If you can't, WoW and crosswords await you.
