I won't try and argue that the ooze form was ridiculously powerful before, it has recently been changed to be useless in most situations. When it had immunities to criticals and sneaks it allowed you to have a great escape wildshape. Without those immunities, the low AC, AB, and damage means this form is relatively useless in most situations. Maybe it can be given a ranged attack similar to mustard jellies - say 1d6+1 acid point of damage per wisdom modifier?
