MMORPGs have an interesting conundrum with levels. As you gain levels, your character gets stronger, so often people expect the game to get easier. However, since it's a game and has to get more difficult as it continues, getting more powerful actually results in the game being harder as the enemies gain power at a slightly greater rate than you do. At least, in most MMORPGs. It's interesting how it works out.
In other news, you may have noticed the goofy "WoW" banner on our hero's back. That's a temporary +12% exp buff that I actually removed just to make Manpanda cool again.
