Luckily I was 53 when the patch hit. I tried questing but was getting nowhere. I ended up grinding to 54 in an out of the way area, which was pretty slow, but much faster than my questing attempts.
From 54 on I've been grinding dungeons mostly. The only time I would consider questing is when the population is under 2400.
If I wasnt close to mid 50s, I would have quit til BG patch. Leveling is brutal.
