Actually the fight with Katarea was because Azazel was mocking her, so he wasn't battling her seriously, that was why Katerea managed to put a self destruct tentacles that will kill Azazel regardless if Katarea is alive or dead. So Azazel just camly cuts off his hand and kills Katarea. Also Katarea's power was boosted by Ophis' snake.

And i don't know how powerful Tatsuya is, but Kokabiel is known to have enough strength to destroy the Kuoh Town to nothing and that Kokabiel is weaker than Azazel.

Plus, you're comparing everything on one standard only. Your standard, which is the LN you're reading. If you actually compare both, yes DxD's character's might be injured more often, but that's because their opponents are that powerful. Try asking your Tatsuya to fight Grendel then, see if he can even injure Grendel much less defeat him.
