This so much. Atomos, melee heavy group, we short 1 ranged for pad. Before I can type out anything another group starts it up. So the other tank and the three melees rush up to Atomos. I know the situation, I stayed back so 4 can be on the platform. Surely I am not the only one aware of our situation? Yet I am the one that got yelled at for not picking up adds when nobody said anything.
There are just so many things that makes a good tank. And you can't always say you must always do this, then that, then that, because, something will not happen according to the scripted plan and you need to change what you thought you were going to do. Trying to pull mobs back in DD from the crystals, especially the range ones, via LOS or just running far back method, and some DPS decides to attack early or healer throws a heal/buff on you? Be aware of the situation.
Like you can kill one of the drakes and have it facing the wall away from group. One of those ranged guys still at range pegging you? Who cares. Shield toss, tomahawk, it will stay on you, and because it is at range, and not melee range, it won't do the AOE attack, so is basically harmless, you don't need to worry about it for now. Instead of trying to get it in melee range, having to dodge both the drake's cone and it's AOE, staying away from the crystal AOE, trying to not get anyone in your group hit with any AOE....
Lot of the little things to have great situational awareness, even the little things that most may not notice but may still make things a little easier.
