Happy birthday cyanidesgirl!
Well, the hard work and focus paid off. This afternoon, while watching Dune and having a rum'n'Coke, I managed to achieve my 4th top rank character. QT3.14 ("cutie-pie") hit level 50 about 3:30pm, soloing against Malta Operatives. Hands down, the fastest toon I've done that with, and probably the most fun.
...and look, not filtered. Don't like it? Suck it.
