I think the point is that Bear group mob tanking requires a lot more 'work' than Paladin or DK tanking by a huge degree - and a moderate degree more 'work' than Warrior tanking. This is not a subjective position. It is definitive and obvious. Feral Bears lack the tools that DKs and Paladins have which make group pulling an effortless process. Warriors also suffer from this, but to not as large a degree as Bears.
Ferals can't bring the group to them. They have to go to the group. Our only 'pull' ability is literally a single target debuff which is on a cooldown. We can tab to one other target and Growl. That's it. After that we have to hope to high heaven that the DPS doesn't start in with anything until about 5 seconds have passed (wait for range, take hits, get rage, use Thrash, use Swipe).
By comparison Paladin/DK group pulling is like falling into a the most comfortable bed you've ever slept in. They can pull entire groups to themselves, damaging them along the way, and getting group aggro to such a high extent that it becomes difficult for DPS to pull even the WRONG target off the Pally/DK.
Bears can't do that. They can't even touch that. All they can do is wistfully sigh and and hunker down as they work their butts off with every single group pull - hoping beyond hope that just ONCE the DPS will wait a full 5 to 8 seconds.
Boss fights? No problem. Too bad boss pulls are only about 5% of a tank's job. For 95% of an average instance a Bear tank is working 4X as hard.
I don't begrudge Pally/DK tanks their great tools. But for Pally and DK tanks to grumble about Bears wanting to have better/easier ways to perform group pulling duties is ridiculous. There are a TON of QoL fixes bears could get that would not unbalance the game, but would make their jobs so much easier. The SD fix will be nice - huzzah. But let's not stop there. Let's make it so Bear group pulls feel less like a chaotic chore. Let Bears have the tools they need to make it so a group pull more about attacking mobs and less about desperately competing with your own DPS classes. Let's have more tools that make the job fun, and remove bad design where you are forced to 'working around' your limitations.
