If your main complaint about Destiny's player vs. player Crucible is too fast, then you should stay far, far away from the recently launched 'Mayhem Clash' playlist. In Mayhem Clash, everything is turned up to 11: Super, Melee and Grenade recharge rates and Special and Heavy ammo spawns. It's absolutely batshit, and you can test it out now: The mode's available for all Destiny players through the Crucible Director screen.
You can watch my first match of Mayhem Clash in the video above. Even if you're not a big Crucible player — which I'm not — it's definitely worth trying at least once.
