Can we please address Darius?
first know that I am a Darius main (sorry) Darius represents everything wrong with tanks/bruisers right now. When he gets a small edge in lane, its completely over. You cannot farm, and once he gets Black Cleaver he can tower dive, period. I think the main problem with his early game is the ridiculous amount of HP that Black Cleaver gives you; it generally makes you the tankiest one in the game. That item would honestly still be good with 0 hp bonus, so fact that it makes you tanky enough to dive is stupid unhealthy. Another major problem with him is his heal. It's stupidly hard to get him low especially after he gets steraks, and on top of that he can survive at around 300 HP for the entire fight because every 3 seconds he heals for 500 or more HP. His Damage or is Tank. PIck one riot. He needs to lose damage on his Q, a longer CD on his Q, or not get the heal from the Q. If a Darius gets a lead in lane, its going to take at least 3 people to kill him, and thats 3 people that can't focus their ADC or APC. Oh ya, and before you can kill him with even a 5 man focus he's going to take out half of ur squishies HP with 1 q and w. I thought the worst thing in this rework was going to be his new ult bonus, but thats honestly not even bad compared to his Q and his.
You can't give a lane bully this much damage, this much tank, a heal, an execute, AOE damage, a pull, a slow, and have his itemization be the strongest items in the game. I'm sure high Elo players are better at countering him, but seriously when you get a 2 kill lead in low elo its over 90% of the time. You can tower dive at 10 minutes, and then it's going to be impossible for the other team to kill you in a fight before you kill their carries.
Bottom line is something has to go; tanks can't have everything. He doesn't die, he does the most damage in the game 75% of the time, and he has utility. He has one of the strongest laning phases of any top laner, yet also has some of the best late game scaling.
He needs a weakness; right now he doesn't have one. Want do to damage? have 4k HP? Have a Heal? Have AoE? Execute 5 people in a row? Pick Darius!
TL;DR: Darius needs either his damage, tank, items, or heal nerfed.
