CWDT flamewall targeting

Triggers always try to target the location/object responsible for the trigger. A skill triggered by CwDT targets the specific thing that dealt the hit which put your damage taken for that skill over the threshold and caused the trigger. If that thing is not a valid target for some reason (such as being yourself), it will look for valid targets in an area around that.

Is there a reason that Storm Call always targets yourself when triggered by CWDT, while Firestorm targets a nearby enemy?

Those skills have fundamentally different behaviour. Firestorm can target enemies, but Storm Call can't - it's intentionally restricted to only targeting locations based on player feedback about trying to place it between different enemies.

Storm Call does not always target your own location when triggered through CwDT. It targets the location of the thing that hit you. Since storm call can only target locations, it targets the location where the damage came from. Your location is a valid location to target, so storm call will use that if you were the source of the damage.

Firestorm can target objects, so targets the object that caused the damage, not it's location - if that object is you then it's an invalid target - Firestorm can only target enemies - and it will look for other objects around you.

Does this mean Cast on Crit skills trigger where the hit that caused a crit landed

Cast on Crit will attempt to target the object you crit - a location-only targeting skill like Storm Call would target that thing's location. If that's an invalid target then it will look for valid targets around that thing.

Triggers from you doing something (cast on crit) try to target what you did it to, triggers from something being done to you (cast on damage taken) try to target the thing that did it to you.

what about flame wall? It doesn't follow either of those rules when triggered by CWDT or by trigger socketed spells when focused craft, whether or not enemies are nearby. Flame wall seems to picks a random direction, and also a fixed distance from you.

Flame Wall can only target locations, not enemies, similar to storm call. If triggered by CwDT by damage from anything other than yourself, it will occur under the object that damaged you (or in the direction of that object if it's too far away).

However, Flame Wall is specifically disallowed from targeting your own exact location, while storm call isn't. Like most skills with a similar restriction (projectiles) if targeted at your exact location it will instead target a random direction (at it's maximum distance).

I don't know why Flame Wall has this restriction (my only involvement with that skill was some advice on implementing the projectile interaction), but it's clearly intentional, so I assume the designers needed it to solve some issue that came up in testing.
