Are you beating the boss? Then it's fine.

Everything doesn't have to be equal. Your job as a tank isn't to be equal to other tanks it's to be tanky enough that your party can defeat the enemies, and as long as it does that you're gucci. So it takes an extra rotation or two, or five, who cares? You're still winning. Comparison is the thief of joy, just play whichever tank you think is cooler.
