I think its better for Ares to just jump and duck projetile while being invisible. It allow him to mask his approach but be weary of using soemthign that give visual cue as they'll give away his position.ares teleport doesnt help him as much as it should with zoners, you can't do anything on reaction with that startup, i doubt he destroys deathstroke, unless his godsmack becomes really good and stays that way i think hes gonna be a fish character with bad mobility.... its a shame his trait is super interesting has so much potential for mindgames.
Ares is going to be patient character for most of his match ups since his slow start up can be exploited. Hes really more effective as punisher type of character since he will rely on his opponent taking the initiative.
