I've never touched the PvP in this game and don't have any interest in doing so for any 'legitimate' reason. But I've considered seeing how things go with boosting the titles with someone else if I ever found someone also interested in doing that. Basically just letting the other person satisfy as many title requirements per match as possible.
Add me on PSN if you'd be interested to try this some evening. Not sure if boosting all of them would be reasonable, but grabbing a bunch of skill ones that can be done in a single match could be cool.

A beautiful loss is still a loss, and an ugly win is still a win.
