This! A million times this.
Its so frustrating trying to do your job and tank the fights, with DPS ninja pulling to speed things up and people flat ignoring fight mechanics. "Off the boss!" on Nazgrim in def stance gets an answer of "No!" - to the point we were almost getting 3 shotted. Its a frustrating exercise but if you want to tank and gear up, its one you have to put up with.
Fate rarely calls at a moment of our choosing...
Just know in LFR if a dps is clueless. The group can still easily succeed.
If a healer is clueless, the group can still succeed.
If a tank is clueless, the group will most likely fail.

A similar situation is when "real" raiders refuse to use the single stack strategy for Garrosh in LFR (aka Stack and Win) even though it is the easiest way to do it, even in Flex. They say silly things like, you will never do it in Normal mode if you don't learn how to do it right here as if that's even relevant to LFR. To me it's the equivalent of splitting into two groups for normal mode Morchok even though he only splits in heroic. In a single stack the tank doesn't have to gather adds, everyone is covered through AoE heals so mana regen is less of an issue for healers, mind controlled players are almost instantly handled through a couple of seconds of AoE, and you only have to scatter while the adds are popping up in the third phase before regrouping and AoEing them down because they don't buff or heal each other like in Normal+. Why wouldn't you want to stack for those benefits? The purpose of LFR is not to teach fights; it's meant to be a step up from vicariously experiencing the raid through a youtube video and nothing more.
Ensidia Fails(requires some config to be effective tho)
DBM or something equalent.
Grid to see the raid and config it so you can see debuffs easier etc. depending on what tank you are and so forth.
Tell Me When - Good for cooldowns, both debuffs and buffs etc.
These are the main addons i use for tanking.
twitch.tv/draahl - Watch me suck at virtually every game!
People should always have been attacking Nazgram in defensive stance in LFR, particularly early on, because groups were wiping due to enrage. If your group is wiping due to enrage, and Nazgrim hasn't received significant healing, then it's just dumb to stand around not attacking him 1/3 of the time.
But it was instantly a "LFR how-to meme" and still is today.
Don't be afraid of tanking. It's quite easy. Just hold aggro and reduce your damage taken. Practice in heroic dungeons. If you can hold every boss through the whole fight and not take a shitton of damage, then your ready for LFR
Just ignore all the internet warriors, usually get's them even more mad though hehe pretty funny to watch. If you cant ignore them remove chat or something and only talk to the off tank.
Second, if you are wiping to enrage ... the INALTERABLE TRUTH is that you must KILL THE BOSS FASTER. That is the only option you have. If there is a period of time where you are standing around doing nothing to the boss, for no good reason (see "First"), then probably you should start attacking the boss instead.
I currently don't tank LFR for 2 reasons. 50% is a lack of desire to learn the tank strats for all the fights and I consider that a must if you intend to tank, at least in a pug group finder situation. There's enough resources out there that there is no excuse for not knowing.
the other 50% is basically OPs points on fear of abuse, and just generally not wanting to put up with any sort of treatment like that.
You must show no mercy, Nor have any belief whatsoever in how others judge you: For your greatness will silence them all!
I'm a main spec healer and have done all the LFR dungeons. I have healed some....OMG horrible groups with completely clueless tanks. Most of the time you will get people like me who are nice enough to give you an overview of the fight mechanics, with really from a tank's point of view are not complicated at all. However, they are indeed essential for completing the boss. Simple things like stand here, separate the two bosses, taunt between stacks (just a couple examples). Anyways, my advice to you is of course, download and install DBM or one of it's counterparts whichever will alert you to what the boss is about to do next and such. Also you tube a few encounters you are unclear about if you want. Do some warm up dungeons then just jump in to LFR. May be a good idea to alert the raid (healers especially) that you are new to the dungeon so that someone can give quick recaps. All in all, don't grieve on what the little kiddies say to you. Fail groups happen all the time and won't go on your FBI permanent record. lol. Practice makes perfect. Be confident and you will do fine.
The groups didn't have the DPS to kill Nazgrim without DPSing him at all times, not until about 5 stacks. They did not have a CHANCE to kill him without determination (even if they stuck to him in defensive).
I did see wipes at 50-100M where Nazgrim had been down to 10-30M and was then healed, but usually that was because a bunch of people started dying in the continuous add spawns and the warshamans healed Nazgrim and everything went to shit. But that was not the typical wipe.
The tank with the debuff doesn't generate rage from his attacks (pretty much everyone knows this) and pets alone don't generate rage either (some people firmly refuse to believe this even with blue posts to the contrary).
It will cause insults and negative attitudes to develop before you've even had a chance to test your skills.
If you haven't got the time to look up a wing before you go(which tbh takes you about 5min),
then whisper the other tank and ask them for help.
