Is this the same for MCH btw? They do share the tier1 and tier2 LBs if I'm not mistaken, but for the life of me I can't remember about the AoE marker on MCH.

In any case, yes, it definitely is way too weird and I'd like to think it's an oversight that'll get fixed....except it's been like this for quite a while and not even a comment on it from the devs. Ok, needs a target to execute, but at the same time, it's also an AoE that's supposed to hit multiple enemies. Kinda illogical not to give it an effect marker when it does have an area of effect.....and I really don't know why it's like this. :|
