These alliances learn from their master...TPF...
Not to take a poo on these alliances...they entered, they contributed and now they are surrendering. They did their part. Let's be honest though OPP is a meatshield group at best. They are use to TPF giving them easy and not so numerous opponents...their not use to actually getting attacked back and in numbers.
The real question is...when is TPF going to follow with their fellow OPP members...
