In his description, Arty’s artillery calldown is described as a means to effect area denial in outdoor spaces. Currently, the artillery strike’s duration is incredibly short over a very small area, meaning that it doesn’t really act to discourage anything once it starts happening – it either does damage or possibly kills, but it doesn’t hamper enemy movement or provide any dissuasion to move through its effects.
Could we possibly see the artillery strike have a longer area of effect? I mean, stretch the damage out for the duration, sure, make it so that entering into it isn’t instantly lethal, but it should still serve a purpose other than being something equivalent to a single explosion of Skyhammer’s airstrike.
