Here's the full Tychus announcement, with writeup.
Looks like he has:
It was changed on today's patch (4.4.0), according to the patch note: > Mutalisk range increased from 3 to 5.
> The Mutalisk's Vicious Glaive will now increase each Glaive's search radius from 3 to 5. It previously increased it to 4.
> The Mutalisk's Sundering Glaive upgrade renamed to the Severing Glaive upgrade. Each subsequent bounce of the Mutalisk's attack now deals 10% additional damage.
The reason for that change was in the Kerrigan co-op mission update (by Monk):
> Mutalisks are challenging to balance for a co-op audience, because like Wraiths, there were initially designed as harassment units to be used in a Versus mode. In addition, both Swann and Kerrigan share the problem of owning another unit on the ground that fulfills a similar role, the Goliath and Hydralisk respectively.
> Our solution is as follows: as with the changes we’ve made to Swann’s Wraiths, we’ll be looking to lean into the Mutalisk’s harassment fantasy as much as possible. The changes we’re thinking of for the Mutalisk are designed to allow players to hit-and-run enemies near the outskirts of their maximum range. Hopefully, when players use Mutalisks in this fashion, they’ll be able to deal massive amounts of damage without taking much in return. That being said, they’ll still be as fragile as ever, so a-moving into combat is not advised!
Numpad 0 might be bound to do something with default keybindings. You can change the hotkey to anything you want, here is a list of the syntax for hotkeys.
To debug you can add a line with
MsgBox, hello world
for exmple directly after Numpad0:: and see if the message box opens, meaning the hotkey triggers. If this works, try seeing if the functions CheckHeroSlots() and CastAbility(n) are executed (every three seconds and on pressing an outlaw hotkey, respectively), again by adding a MsgBox line.
Also, you can bind the InspectColors() function to a hotkey (at the end of the file!) and run it while having selected some outlaws, like this:
Numpad5::InspectColors()
Compare them to the color values I got on my machine.
Strictly by bullet point count*, Karax, Swann, Stukov, and HH got major updates, but 9 other COs also were in on some minor updates.
*. whether or not they've been that effective is another thing entirely
A co-op balance update was released a few days ago.
Overall goals were improving the ramp up time of slower commanders and improving less used units across the board.
They also fixed the polarity bug. It's at the bottom of the page. https://starcraft2.com/en-gb/news/22883350
Fixed an issue where the Polarity mutator would display its icon over friendly units and structures.
