I know that raids is still being tweaked and we're long awaiting for any kind of drop rates to be released regarding chests, but my suggestion is more about a competitive side of raids with the addition of a completion timer,
This would be very good for general QoL but also for the players that want to hone/fine tune there performances and know if they're being efficient or not.
Maybe, along side this, with some version of hi-scores/leader board in game ( not necessarily giving any rewards or benefits) just abit of competition and bragging rights.
Thanks Ashh,
