Melding lore 220 /midas with just one or two Acc materias wouldn't cut it, even close.
According to your Lodestone, you currently have 444 accuracy on your WHM. If you're noticing a significant amount of misses, either you're eye balling too hard or something is wrong with the parser you're using. I say this because of the following comments from a different thread on the general OF:

Heck I'm at 462 and I don't miss in there either.

I ask you check your data again just to be sure because what you speak is a contradiction to some of the comments listed above. My gut tells me the cap for EX dungeons is around the 450 mark.
