F2P Snipers
It is also good for getting Classic 5* Snipers if F2P or
if want multiple copies of Marjana / Leonidas after getting the costume
Rage
Click for rant
But
From a player friendly point of view, the most rage is generated by
finally getting a limited availability hero
already having a duplicate of the limited availability hero
the duplicated hero is still at 5* 1.1 because it does not work well in your Roster, or there are other better heroes stuck at 5* 3.70 waiting for materials ( or in the future limit breaker items )
Not wanting to dispose of the two copies at 5* 1.1 because they may get buffed like Atomos
Looking at the duplicate repeatedly in the future
