I was replying to Fwahm since it sounded like he was expecting a low acc rate w/ Shockwave's AE. The linked update was specifically addressing the unexpectedly low magic accuracy (landing/resist rate) of the added effects of the listed weapon skills after they confirmed a problem with a GK ws and did a pass on the rest. I kept hearing that the update worked great from lsmates, so seemed odd that the rate should be low against anything other than dark-resistant mobs.
Fwahm: Since I imagine that it's going to be tricky to get accurate numbers on mosquitos due to not knowing their actual dark resist values, maybe try something else?
