Peacekeeper's top heavy finisher should be unblockable

At the moment, she is the only hero in the game without some form of unblockable or bash attack. That doesn't inherently mean she needs one though.

The reason Peacekeeper needs some form of top heavy unblockable is because any attack (besides an opener or chained light) that comes from the top is useless.
Peacekeeper's main offense is her dagger cancel, so attacking from the top is just shooting herself in the foot because she completely cancels the mind game that the dagger cancel brings. There's no real reason to use her top heavy finisher because it, once again, negates the ability to properly force your opponent into a mind game by using the dagger cancel.

Now, if she had an unblockable top heavy finisher, she could not only attack from the top, but also apply even more pressure through direct damage with said unblockable, and have a reliable way to get OOS punishes by forcing OOS players to play into the unblockable mind game.

I see this as a beneficial change, not only would it completely revamp her offense, it could help her pressure heros like Conqueror, Warlord, and BP who shut her down pretty well with their option selects and full guards.

Oh, also, please give her frame advantage on dagger cancel.
