Roach isn't really on that much, and Tronga is on at time when Roach is not. They can lift the burden off of eachother, give each other some relief (... sickos

Plus, Roach can't really hande all the ideas and every complaint and every suggestion on his own. It could also give Roach a little bit more time to do what he wants to do, and be a bt more active in his posting.
