Riot should use the current assassins that build tanky as a templet for divers.
Hey all I wanted to talk this issue as currently we are in a meta that is dominated by assassins that are building defensive items(and Not I wouldn't be calling them Tank items, Being a tank rests on their kit, not their items but it helps them out) So, I wanted to highlight what really needs to be done for balance if riot are going to balance the Divers update after the Assassins.
**Offensive and defensive scaling is out of control and needs to be fixed!: **
Ok, so dealing with the first probelm and that is that assassins are becoming Lighting bruisers(Link: http://tvtropes.org/pmwiki/pmwiki.php/Main/LightningBruiser) Now, I fucking love them, but their is a damn limit and the stats radio is completely out of whack. Having the Likes of Ekko, Fizz, Yasuo and others stack some armor after they have some offensive items if absurd, seriously their kit gives them insane mobility and damage and not with the baseline power of defensive items, they are abusing a serious flaw, as if they are rapping the hell out of it. now that is a reason as to why it needs to be fixed. It also makes it so that Tanks are no longer needed in the game, so get two three assassins building some resistances and they will ruin anyone that faces them in a team fight or even end you 2v1. that is not balance and it needs to be fixed.
Riot Could Learn from this fiasco: Look having fast moving assassins with the durability of juggernauts is not good for the health of the game but, BUT! They could use this as a means to balance divers because assassins have become sup'ed versions of Divers so could use this as a foundation to fix assassins while at the same time preparing drivers to better tunes before going on to fixing tanks. It's an idea that I do believe can fix this issues with OP assassins killing while never being killed.
Balancing Durability, Damage and mobility will be a bitch for sure: Look I am not a part of the balance team of riot, I wish I was but I am not and can't but I want to do a bit to help anyways. Balancing should be about them them itemwise having to build a mix of them instead of jugg's that build one more defensive item for themselves compared to them. kit wise they should be about dealing damage while at the same time being tough enough to take hits also, unlike tanks being in need of timing their dive right. Unlike tanks or to a lesser extend, juggernaut, who can at least survive long enough to deal a bit of damage of disruption(generally) they really should be balanced about the whole idea of them jumping in and messing up the enemy team while they are like; OH SHIT! while the diver is laughing like a maniac killing them off. some will be tougher(
) than others (
) but that is just their own individual style. The Cool part if they get balanced right, will mean that they will be a toned down version of the assassins that we have, but if not, well, history will repeat itself and people will be pissed.

** divers instead of assassins:** As was mentioned in Redmercey's (Link below) Video about fake assassin's: some assassins are not really living up to the fantasy of being stealthy killers that jump in and kill quickly before retreating or letting their team jump to the rescue or assist them, Fizz and Ekko have more or less proven themselves to be divers as they jump in and wreak havoc on the enemy team before retreating and are nimble as hell, so even the assassin or the diver update happens, they should be moved to the diver role and get tweaked to that they are more balanced.

Anyway this is just my own two cents on the matter. Peace.
