I mean, you might think that it would be obvious that after a huge pull, when the healer somehow managed to keep everyone alive, but is OOM, that waiting a few seconds instead of facepulling again immediately afterward would be obvious. But that is not the case.
Instead, I have been given the role of group speed moderator. Everyone else just wants to mash everything as fast as they can but I have to be the party pooper asking everyone to slow down, just so that I am able to do my job.
I've played since early Vanilla and played a healer almost that entire time. Early cataclysm was the only time in that 8+ year history that I actually quit the game. It just wasn't fun as a healer feeling like you didn't have the tools to do the job. It's not fun feeling like everyone else has to change the way they play just to accommodate your needs (drinking for mana).
And that's if they even speak English. Nothing more fun than a Brazilian tank who constantly pulls at 10% healer mana and you don't even have the option to communicate the problem.
The only tool at my disposal here is to let people die, which 75% of the time just results in me being vote kicked.
The key to getting past the mistakes of cataclysm is not to repeat them. This really isn't looking good.
