DPS display could easily be solved with a system already in game.

Unfortunately, our arguments are both based on at least some speculations.

Your examples are anomalies. My examples contain what is majority accepted. Which would suggest your argument is pretty weak. The reason we don't see unrealistic expectations like i130 required dungeons,primals or what have you is because the majority have an understanding of the required DPS to complete an instance.

It is not enough proof to take action on, is the point. Like I said, I could claim I bot/hack/buy gil/etc in the game here.

Go ahead and claim it, include the site and/or bot you buy from/use and lemme know how that goes for you.
