LOL! Face was Mard Geer's master plan to take out humanity because Tartaros couldn't beat the humans in a straight fight (they lost to just FT, without people like Jura and Jellal helping out). If Natsu exhausted himself fighting just Mard Geer, what makes you think he was going to single handedly stop face?
This was Jacob's reaction to the heat coming off of Natsu's FDK mode. This would have happened no matter what position Jacob was in. Jacob could have been on the ground, hiding behind a metal shield, and the heat would have still caused him to burn up like this. I shouldn't have to say this, but you can't physically block heat with a movement.
