Post your experiences here!

I'm currently rolling ghetto with an A2 Might Merc rocking non-eth Reapers Toll/Crown of Thieves/Leviathan
Playing as an IK/HiLords/BK/Natures barb frenzying Stitches through Infernos. He survives when there's no OP champ mobs around.
His ctc Decrep is great for slowing Griswolds and almost completely stopping regular Hephastos (not to mention the Decrep killing phys immune while waiting for that damn legendary mallet to cast amp)
Extra Fast/Cursed mobs good luck.

Anyways, what merc is benefiting your current character?!
