Lots of laggers playing Destiny. Lagging can be considered cheating, if they are doing it intentionally. Just put a linux computer between your PS4 and router, or between router and modem. Then use iptables to make yourself lag. I’m sure you can find instructions on Google.

Good enough reason not to play the competitive multi player in Destiny. Don’t think I’ve seen anyone lagging in the co-op. But you most likely won’t see anyone. Everyone is most likely playing the expansions now, I don’t have any expansions. I don’t put money into a game that is supposed to be co-op, but isn’t, cause nobody plays with me.
