no, you don't know alot thats why i'm correcting you.
i don't know the facts kid? i've been playing this game longer than you've been through puberty

everything i've said is true, most of what you said is bullshit your ebay le3t friend told you. refrain from posting unless you know what your'e saying is true/real.

yes DR% works on mercs
thats why people use eth gazes/shafts on them.

edit : but most of them would die in 1-2 hits anyway so they try getting most dmg out of them ie edmax helm/armor or edias depending on merc type
