He's already changed a few aghs this patch so I'm sure that'll happen more in the upcoming patches, they're now hero upgrades rather than ultimate upgrades. Seems like he wants the item to be a niche option that you can get in specific matches, which I like.
Lots of people think most of the aghs upgrades are dumb, and some of them might be, but I'm sure most of them will turn out to be useful in certain situations.
What I also find interesting is that he reverted/reworked changes such as Legion's so quickly. It was clear that endless duels weren't really useful (outside of endless Nightmare juggle scenarios to tie down the Legion forever), and rather than sticking with a pointless Aghs for ages (such as the old OD aghs which was mathematically worthless), this time around he's chosen to rework something quite quickly.
