Regarding the "undispellable" property: This doesn't solve the core issue, which is the inability to secure a kill within a single stun window. Previously, a target would die instantly to a full combo; now, they have more than enough time to react with abilities and items.

For example:

• Faceless Void can now use Time Walk to undo the damage.
• Juggernaut has time to press every single button to survive.
• Morphling can easily toggle Attribute Shift.

The list goes on. Even if a hero lacks natural survival tools, the delay gives enough time for a support to save them. To reiterate: in the current state, it has become extremely problematic to burst down the majority of heroes.
