I disagree on this premise. A tank is expected to do tank things like aggro and mitigation but if both are well taken care off, there's no other thing to do but to contribute to the entire raid's dps. The very reason I don't stay put on other MMOs is due to this reason alone. They're shoehorning tanks to be nothing but pieces of meat that only exist to take damage, nothing less, nothing more. While it works, it's not always that tanks are in parties to do that. I've remembered playing this once famous MMO in the past and as a tank, my damage was non-existent and am begging for other jobs so i can leech exp.

LEECHING is the cancer of MMOs, second to RMT. And that's why I liked on FFXIV. Even as I tank, I can still manage to do decent amounts of damage and be self-sufficient if need be.

If people wanted the meat shield tank, then go full fending. No one's stopping you.
