People love to make things complected.

It is the tanks duty to pull and hold enmity, not yours. Focus on your primary role and let the rest of the party focus on theirs.
At the end of the day, it is just a simple duty. Don't make it harder than it should be.

Tanks can be slow for multiple reasons.
- New to the role/inexperienced.
- New to the dungeon.
- Under geared.
- Disabilities.

If these things don't matter to you, then prepare for potential wipes.
Don't blame your tank if you do wipe. It was your action that caused it. Your action, you take responsibility for it.

If you do not like being with a slow tank you have two options:
1) You kick the tank.
2) You leave the party.

But the best option would be:
3) You adapt to your slow tank.
