Why Ash's Marked for Death is OP.
Let's Begin Shall We?
(Marked For Death: Your Map shows the location of recent death boxes. Can use a death box to reveal surviving attackers.)
When I read this, It sounds like a great passive for a scout! Why I can think of a scout hero that would really love the second part of this ability *cough* Crypto *cough* seeming as he's all about hacking and manipulating tech. Hell, I can even imagine this passive being added on Bloodhound seeming as he's basically THE hunter tracker. But sadly, however, this isn't on a scout tracker. It's on a DAMAGE DEALER! Revealing and tracking enemies is the scout's job, and the only hero that can reveal enemies while not being a scout tracker is Caustic due to their traps. So why does a passive that can notify you if someone dies nearby and reveal enemies on Ash, A Damage Dealer?
At least remove the ability to reveal enemies through a death box, as it effectively makes using an actual tracker to reveal enemies pointless.
They still have their uses, but combined with everything else, she's basically a crowd-controlling, teleport-making, tracking damage dealer. Why play anything else?
