So, from what I understand, you require to do mechanics in order to be able to not deal with enrage stages, this could be easy for static group to adjust improve and carry on, but this isn't good at all for pug groups, as well as solo players, even though it is hinted out that the further u go on, the harder the stage will be, as it seemed we don't know what kind of surprise is waiting for us for stage 5 weapon.
however, it has been months since sorties release, and we haven't figured out ixion nm in F area proc requirement, could be nice and give us the proc, since some of stage4 prime players would require it.
