Aye, last time I even decided to log on I ended up getting my GLA PL'd up a bit... but only because I couldn't actually get a real party going and then my LS mates offered some power leveling.
Now, if I were staunchly against PL'ing I coulda just turned them down and continued to shout for the two hours I had left to play for the night... but I'm not, so I got free levels for about an hour and then chilled out for a bit before logging off.
