Instead of reworking all of the juggernaut/divers
We could just buff tank itemization/nerf damage itemization. The current issue with Divers/Juggernauts isn't the same issue that tanks have.
Tanks typically (should) have an issue of dealing damage, because they are high cc, and should be building tank. Issues typically arrive when these guys deal too much damage, or die too quickly without being able to get their cc off.
Divers on the other hand have no issue dealing damage, what they do have issues on is getting to their targets. While Items like Deadmans plate, and stereks can do a great job shrugging off some damage to try and get to the adc they seem to be falling a little short, which leaves juggernauts either building full damage, or full tank, and not being able to do their job of soaking damage while wading into the enemy team to get to the enemy adc.
Now if we were to buff tank itemization or nerf damage itemization, we would likely have to nerf some of the outlying tanks that have decent cc and mobility mao, sedj, zac. However as it stands divers currently need to be reworked because they can't function as is without being hyper nuke (akali), or just a cc tank, which is why riot needs to add gimmicks like xins new ulti.
I suggest making tank items gold efficient, or we could just deload ad items, most of them have extras that they don't actually need. The last thing we need to do is stop generalizing everyone that at one time built tank as tanks, and nerf damage champions appropriately when they build tank fizz fiora, yasuo and ect...
Also, in my opinion, the way to encourage damage dealers to deal damage is to increase their ad ratios/ap ratios, but make them have less base damage. This forces them to build higher damage to have damage, but allows them to also scale quickly with damage purchases. One way to limit their damage if it is an issue is like doing old poppy's Q. Where she could do a maximum amount of damage based on the skill level.
As for itemization: I strongly believe Tanks/divers also need options like Qss, and an upgrade for it.
Please don't just downvote and move on, lets have an actual discussion.
