Indeed that +30% exp under lvl 30 is pretty sweet. on top of that you can use that ring from the training grounds to get a whopping 60% exp boost all the way to 30. So total if you already have a class lvled up past 30 your total exp will be 50% + 50% (under 50 boost) + 60% (ring + Eastern Garb) + 10% (FC) + 3% (food) = 173% exp boost and if you have rested exp that's 223% total. Too bad that ring cant scale all the way to 60 xD.

223% total exp boost isn't too shabby.
