Shortage of tanks a myth - thoughts?

[Sapphic]

You have the entire party in your hands. You and the healer are like bff's both stressed to hell. xD I'm also scared of playing 'Tank Wars' in WoD.

If people make a genuine mistake I make a light hearted joke of it (not turning them into a joke of course) so people relax, if it's a mistake from lack of experience I give some tips on what I find a good way to handle it. Not saying as that is what they should do, but for eample "I handle that by doin this". If they go all jerk on me, and continue doing the same thing wiping the party, ill suggest in party chat to remove them.

Oh and in the CT dugneons. If I'm tanking and they start provoking off me, ill stop hitting it and leave it on them. They want it that badly, they can keep it. Ill just pick it back up if they die.

Speedpulling is part of the reason people get rightfully upset, because the tank never ask the healers what they can handle, nor do they look at what DPS configuration they have. Two Melee's, forget speedpulling (they will get creamed by the mobs AOE's, regardless of gear.) Two BLM's, Speedpull as much as possible if they are overgeared for the dungeon. BRD and SMN? Probably not going to happen.

I always ask when I tank. So incorrect generalization there.

Also 2 well played and well geared melee are perfectly capable of speed running. B4B+ perfect balance, spam rockbreaker with MNK. Also Ive done speed runs with pretty much every combination of DPS jobs there is.

There is an entire argument in the healer forum about this.
1) Tanks should tank, Healers should prioritize healing, and DPS should DPS
2) If Healers are DPS'ing and DPS are healing, then you've dragged down the DPS output of the party.

So what should tanks do when they arent tanking the boss? Sit around scratching their unmentionables? Or what about healers when theres a lull in healing needed? Watch netflix instead?

number 2 makes zero sense whatsover. So if DPS are doing averge 500 DPS thats 2000 DPS. tanks are doing average 300 DPS. thats 2600 DPS, and if healers are doing on average 150 DPS, that takes the total to 2900 DPS for a 8 person party. How is that a DPS loss if healers are adding to the damage. Who said anything about DPS healing?

Indeed Melee's (particularly Ninja and Monk) seem far more likely to not avoid AOE's. More than half the 4-man parties that have one or both, increase the healing requirements in a way that the healer can only save the tank or the DPS, and it will always be the Tank that has priority.

MNK are far more likely to avoid AE as they are constantly moving anyways. Only bad melee eat avoidable AE. So stop trying to catogarize all melee as bad.

I get it, you cant do speed runs, but making up imaginary generalized arguments against it is weak.
