Roulette Abuse?

[Ninix]

Well i saw not only tanks droppin , but dps & healers too . Atm what i doing is taking screenshot right @start so i know who to report lol

Report them for what? Leaving a duty is not against the rules, even if it's done immediately after zoning in. It's inconvenient for the other players, absolutely, but it's not actionable behavior. You're just wasting GM time and making support queues even longer than they already are.

The game already has a built-in penalty for doing this sort of thing, it's called the 30-minute leaver cooldown.
