Change to accuracy seems to allow the dodging of beneficial buffs
So, the change to accuracy seems to have introduced the possibility of dodging beneficial buffs from people of your own level. I was "able" to dodge a Bard's song earlier on MNK and looking around on the web I saw that some Summoners are reporting that they were able to dodge their own Dreadwyrm Trance.
The latter sounds like a bug because it messes up your rotation entirely, but if the former is a feature I really don't like it. Beneficial buffs from party members shouldn't depend on RNG to benefit from.
