Should Tanks have low AC?

[Demonslayer666]

Don't be too harsh on GMs running "dumb" enemies using effective tactics, after all many Int 8 PCs use brutally efficient team tactics.

Certainly not doing that. Just stating what I do with things that cannot identify a mage or cleric.

...
The fact of the matter is, almost everything in D&D land is smart enough to employ decent tactics.

I strongly disagree. Most things cannot identify a mage/cleric in the party and know that they should be the primary target.

Even wolves don't have hunting strategies that reduce to "attack nearest thing."

That orc with 7 Int? They possess instincts honed by a lifetime of warfare, and were trained as a soldier in a battle-hardened warrior society, taught tried and true strategies developed over generations of trial and error in battle. They know what a spellcaster is and why it matters as surely as any modern soldier can recognize a tank, sniper, grenade, or artillery emplacement and has at least some idea of the correct way to respond.

A low intelligence score is not a good excuse to play creatures like badly programmed videogame zombies.

Wolves cannot identify a mage and single them out as the most dangerous, targeting them first. That's not something wolves do in the slightest.

You and I disagree on the amount of training an orc has. Orcs are certainly not seasoned veterans of war. They only have 2 HD.
