-Regarding the "load for load" topic, it's a natural and fair thing. You made a mistake, and you gave your opponent a chance. Maybe the first person to take the load will actually benefit more from it; who knows for sure?)
-Regarding "shun-dodging": firstly, the main motive for such an action is playing for real money, and secondly, it's a lack of respect for oneself and one's own skill.
-And regarding joining neutral creatures: I've never seen anyone join me on IRMG maps in Team Edition. And since you're so afraid of such minor things, Elemental, there are special settings for neutral creature behavior that can be configured so that they never join at all. Furthermore, mixed armies by default never join. I hope that's enough arguments.
