Lets stop fighting SE and work with them. What are your ideas?

If we have a massive aggro lead but the DPS are not utilizing it, what's the point of us doing our damage combo when it is going to be significantly less impactful?

I don't understand. If you want to have massive aggro, you'll probably need your tank stance and a use your enmity combo a lot. Right now, this "rotation" would lead to very low personal DPS. If you want high personal DPS, you'll drop your tank stance as much as possible and do only the minimum required enmity combo.

This would not change with my idea, apart from having a more complex enmity rotation. If your DPS can not make profit of your enmity, then it's better for the raid if you stick with the current focus on personal DPS. In that case, your personal DPS would still be impactful when compared to your DPS (low) number.

tanks are designed to be side kicks/Robins to our DPS heroes/Batmans than equal team mates.

We're not sidekicks. Without us, the whole team would die in mere seconds. It's the exact same oversight as those who consider healers as "cure-slave". We've seen synced content done with a team full of tanks, where are the "full DPS" team that cleared the current savage raid ?

What's the point of us using big swords/axes or even straight swords if they do nothing?

Sorry to disappoint you, but it's a trinity based MMO. You could wield a litteral nuclear bomb, if you're a tank, you'll do less damage than a DPS using a harp...
