PC Shing Jea Greens...

What are pre-searing greens worth? Are they basically something that I should just throw away if I don't plan on using them?

Pre-searing greens O.o

I think you just mean Shing-Jea Greens. And yeah, just throw em away.

Or you could, in a strange act of generosity, give them to new-ish players for free. =)

stick em on heroes or give them away
