I disagree with essentially all of this.Stuff
And again, NO ONE should be asking for ANYTHING other than bugfixes when the patch is so new that we don't even have it on all platforms.
Also I highly suspect most of what you're suggesting is the result of groupthink rather than your personal experiences.
Unbreakable damage is still good. Some characters have X-rays that scale very nicely (Ermac), others have X-rays which allow them to burn meter for damage when they have no other way to (Cyber Sub, Jade, Noob), while others still allow you to land big damage from an AA combo that might be difficult or impossible to otherwise (Noob, Kung Lao). There are more examples than these.Ya that I get, but people do xray combos that WON'T end the round, not by a long shot.
A few other reasons:
Being hit with a 60%ish X-ray combo is extremely demoralizing and can make even good players do something slightly more desperate than they should.
Putting someone into chippable health without causing a KO can still render their breaker useless.
You may not be afraid of the opponent's combo damage (Jax), and thus not worry as much about using your own breaker meter.
Also, and this is often overlooked, soul steal X-ray combos kick ass and are even more demoralizing.
