I'm behind a level sync system. It can lock out or just make higher level abilities on your class less powerful.

It's really irritating when I'm trying to do Toto-rak "Right" with a class in the right range and 4 people, and one of them decides to change to a rank 50 and blast through. Just had this happen to me and it was totally lame. The SECOND I started to talk strategy, one of the other plays essentially said Screw this, went 50 Gladiator, and took off through. Kinda made me mad.
