In the Avatar arc he didn't just get up from a coma after almost dying to the point of his heart actually stopping to beat.

Usually people don't just hopp off their deathbed and are immediately back at full power. This situation is nothing at all like the Avatar arc.

And you dodged the last part: How is Natsu supposed to defeat Jacob, if he can't connect with any blows? One-shotting only works if you actually hit the opponent, but it's hard to hit an opponent much faster than you and capable of completely masking hismelf to any and all your of your senses.
