I've played evil conjie, and I've figured out how to overcome your problems. You apparently have not. That doesn't mean that evil conjie is either a deathtrap or unplayable.

I don't need no-fol to handle evil servitors.

You clearly just piss them off big-time, AND you can't handle them when they are angry (which isn't that hard).

Their survivability is just fine. Unless you plan on always using demons vs ragers when you have no protections. You may, however, need to show minimal tactics such as letting your enemy come to you sometimes so that your servitors are already wiht you, and will therefore assist pretty quickly.
