Guild Wars 2

Needs to hit Infinite Targets.
Needs a much bigger health pool, can be traited for invulnerability.
Needs to fire on its own.

An intresting Idea, The infinite Targets might be a little much but traiting to fire on it’s own would be something, come be used very tactically before a major fight to bring support.

Inf targets: bad idea
More HP and traited for invul: not really the problem with it
Fires on its own: This is a good idea, the problem with the current mortar is its far too weak to justify losing your weapon and utility skills while using it.
IF it would be changed to work like the other turrets then it would only have access to its normal attack and the concussion barrage would be its overcharge.
Instead of the overcharge just changing its next attack. It could let you indicate the aoe, like radioing in an artillery strike. That would be cool.

Honestly, I would probably take it for WvW if that was the case.
It would need a new model to separate it from the manual mortars.

They’ve said the target limit is due to a technical limitation

If they changed Mortar to a kit; it wouldn’t need a higher hp pool since there is no secondary target for the enemy, it wouldn’t have to rely on kittened AI since its not firing on its own, and it would solve issues w/ positioning/range

And two turret elites is redundant as Supply Crate already includes turrets.
