Riot's Innate ability to in reworks to completely screw up champion balance

NOTICE: I'm only talking about the recent juggernaut changes and some info on previous reworks if it comes to mind. Also my points of contention are specifically from a casual gamer who doesn't play much ranked.

First and foremost, I would like to address the elephant in the room. The recent juggernaut changes are broken. From what I could remember playing the reworked champs namely Fiora, Garen, Morde, Skarner, and Darius most of them pre-patch were decently enjoyable to play with the exception of skarner. Fiora had her annoying early game ad steroid which made trading with her not an option unless you were begging for an early death. However she had no escape to speak of and late game could easily get blown up in teamfights. Now her early game trading in my opinion is even better (i shifted positions on this) with the %max health true dmg passive compared to the early bonus ad. She has some cc now (compared to just the attack speed buff she had), and she most importantly has escape. From my personal experience ONLY, fiora tops used to have a wide spectrum of effectiveness in a game ranging from absolute snowball monster, to decent, and just a squishy meat shield. Now it seems its just the first and last options. Fiora either just dominates the early game and gets an unbeatable advantage (i once had a fiora do a total of 1k true dmg to me), or just for lack of a better term crap.

Moving on to Garen, his q got hard nerfed, his w nerfed (no tenacity, the armor/mr bonus is relatively even i.e. slightly better mid game, worse late game), and the buffs on his e and ult are at best situational and at worst useless. Granted he does true dmg on his autos, e ticks, and ult but its ONLY for the targeted villain which 9 times out of 10 are in some other lane or the jungle. Out of the 5 recent reworks (counting Fiora), he is by far the weakest. Darius, his Noxian counterpart, on the other hand got some MASSIVE buffs and deserved bug fixes. The bloodrage passive gives him Fiora level trading potential, and a massive AD bonus. Albeit his q got a nerf with the delay, but i think more often then not the healing factor of it makes up for this (unlike the silly veigar e nerf). With his w and e remaining relatively on par with what he had before, all thats left is his ult. WHICH AT MAX COSTS NO MANA. This ult is a much better execute style ult then garen's ult ever will be.

Last but not least, I've grouped Morde and Skarner into this paragraph specifically to address how stupidly broken both champs are in their current state. Skarner while at any of his shrines at ANY point in the game, literally will NEVER be down in mana when clearing camps. This is also an indirect buff to mid laners to an extent considering skarner now can easily play around his shrines to never run out of mana. Then comes his stupidly OP e, and the massive w shield he gets. Not only does the slow on his e last longer then two seconds, he can easily pop the %max health shield to catch up to someone and auto them to stun. His dueling potential in basically unrivaled for bruiser/tank junglers. Morde is potentially EVEN worse with mainly his low CD q. 390% AD scaling and 280%AP scaling. What. The. Actual. Fk. I've literally at times just charged up to the third q proc, then flash auto ignite and walked away to watch them hopelessly wander around to await their nearly guaranteed death. Much like the aforementioned reworked champs, his dueling potential is arguably the worst among the recent reworks. Plus who doesn't want a dragon pet that chunks turrets?

PS: This post was my very first one and done late at night after school. Forgive me if I didn't make the most coherent of arguments anywhere in my post. And please if you are going to criticize my post (which is inevitable), make the criticism constructive at least.
