depends on "were, when & how" if we die say tring to free Al Mhigo in the new X-pac it give Garlean all the reason/power they need to stomp Eorzea to dust (especially if they save our corpse for proof or trophy) if we die in some massive battle against something else infront of say all GC/City leaders well yah MASSIVE panic especially if a large group of civvies also see it... killed while escaping Ul'Dah in 2.55, Heavensward never happens as told war there lasts for a longer time (as the Archbishop stole the key from us he couldn't kill Bismark before then or else he would have & the Garland empire would have free roam of all that tech, waring triad & bound 1st brood Dragon as they got in without the key). Now if its a isolated moment with say 1 bad guy and he & the few ppl who saw say nothing then the fallout is less at 1st giving time for eather a) our "Phonix" return or b) our "replacment" getting up to STR
