Quick question about Unique

so here is it , lvl 128 and getting this crap,  not to mention that it’s my 3rd same unique, and that I had a better stats on the one that I got when I was on lvl 115. 

Is this a bug ? or that’s how the game is set up! ?  I mean getting a useless unique it’s kinda hurts ???

That has nearly half the cooldown of my Gemini. 

I hope devs do something with repeat unique items… Maybe same uniques should forge eachother making a great one…
