I don't think there's been a single MMO on the market that offered ranked PvP where this wasn't an issue. Every time a system is built, you're going to have someone come along and attempt to game the system for maximum benefit with as little effort as possible. Welcome to the human race.

And to be clear, I do not condone it at all. It's sadly though something that is going to be done regardless of the mechanics used to try and limit it.
