It does not stop Vial only, but stops planeswalkers, jitte, ravager, smokestack, coralhelm commander and others. We'll just have to wait and see.
It's not the B that is the issue, but the X. If I have to spend 5 mana and 2 life to remove 5 counters from a Jace... I'd just rather Vindicate it or attack it. For Vial, paying XB to get it to 0 and then 1B or 1-2 Life every turn just to make sure they don't get to two seems... very lackluster. Again, what are you going to take out to replace it? You have to take something out. Nothing is worse than this, therefore, it's not going to see play.

It doesn't stop Jitte. It takes one Jitte counter and makes them use it on that for a card from your hand. It's too narrow. Everything else you mention can be dealt with by something else more efficiently. Especially because this doesn't "solve" anything but Jace as the other counters will come back.
