Respectfully, that seems counterintuitive. Top lane as a whole has been complaining about lack of agency for quite some time - tanks included. Nobody really feels like they have much impact at all. These changes seem to take part of the little agency that tanks have and redistribute it to fighters. Now, don't get me wrong, I'll be glad to see more fighters in pro play, but this feels like it's going about it the wrong way. The goal should be to have all top laners feel like they have more agency, whether they are fighters, tanks, mages, or adcs. I hope I am wrong, but from your explanation it sounds like Riot is robbing Peter to pay Paul with this patch.
This is not the silver bullet to top lane agency. The primary goal is a pro play meta shift. The tactics are those that ask top lane to care more about gold income.
Many top laners are better than all bot laners at converting early leads to game victory. Few top laners are better than the average bot laner at converting mid game leads to victory.
The calculus is not as far off as many people think, but it would require many more changes than these to reach parity.
