Why is it always the baddies that decide that they know best? Watched this alliance tank sit there telling off other tanks for spinning the boss before they proceed to spin the boss themselves, killing a handful of people because they ignored a simple mechanic and had to run to a cleanse pad. The entire raid they used only a handful of mitigations which was ridiculous.

I swear it's very, very rare that I see people that know what they're doing get aggressive or take a bossy attitude towards the rest of the group.
