OOGOOA defence / support planets

[Wishmaster]

First i like to state that I hate the rule, hated it when it was enforced and would hate to see it enforced again.
The question that arises for me though, is how the pa team / mhs in r15 suddenly saw fit to add a new rule when eXi used out of tag planets to defend them, and escort / attack with people in main tag.
Now that asc have been doing the same the past 2 rounds ( I did the same in omen to a smaller extent also granted, cause as I said I dont like tag limidts ) the same people that played against eXi and cried for the rule to be enforced are "abusing" it just like eXi did. And no one in the pateam seem to care.

Whats the difference from r15, to r31 pa team? Why Make a rule midround once, and not do it again if another ally use it even more?
Is it because asc got more "friends" in high places than the hated eXi did? Or is there another reason?
