skill is fine as it is, it should keep its low proc rate cos if it does end up proccing mdef debuff its almost the mdef equivalent of 0pdef, which we all know is not very interactive. mdef debuff is also the only debuff that is worth proccing, others are arguably negligible. not to mention wf is more than fine as it is, honestly you can even make an argument to it being overpowered and more in need of nerfs, rather than buffs
