First the easy question - is there a reason why the Yugia patrol tokens have little arrows on the 4 sides of the tokens (looks almost like a compass)? I wasn't sure if they were just for show, or if a Yugai in an adjacent space SUPPORTS a Yugai which is in battle (hence the arrows). I read the rulebook but it states that Yugai in the SAME space support each other. No mention of Yugai in adjacent spaces.
Originally, the YCU units added the value of all units in adjacent spaces, and the + was a reminder of to add all the adjacent Yugai attack values to the current battle. Think of the +'s as an artifact of the design process and play testing... and how each battle could be kicking your booty even harder.
