Looking at the Wiki, it looks like the Quasar is the only legendary, seraph, or unique singularity grenade. Interesting.
I gave it a 4.5. I prefer a Storm Front if I'm working with a shock grenade, but the Quasar is still really good. I used one on my shock Gaige for a while, really enjoyed it. --- 2007 - 2008 NHL Saturday Picks Champion
