I look at it like this; Each Class has 3 total Subclasses. The 1st 2 Subclasses introduced only had 1 from each that was able to Destroy a Bubble. Voidwalker Gunslinger Striker Enter in Taken King and 1 new Subclass per Class. Stormcaller Nightstalker Hammer of Sol Now since Nightstalker was built to shutdown Any Super and Hammers are also bubble poppers - what did this leave Warlocks to work with in Stormcaller? Landfall Altho unlike Quiver/Hammers, yer Bubble popping does not come from the Supers main ability to shock multiple opponents over time. But from a selective perk. So they must have allowed Landfall to pop Bubbles to make it fair. Now if you are still reading I would like to just point one last thing. Landfall can do a total of 3 things: - Damage enemies within the Sphere of Damage Next too and Below - Damaged Enemies are also Blinded for a few seconds - Can destroy a Titan Bubble Now lets see here... Every Super that has the ability to Kill a Bubble ALSO has the ability to 1HKO guardians.... EXCEPT LANDFALL!!! So I also think that because Landfall does not instantly kill a guardian - they decided to add the Blinding effect as well.
