The current state of Tanks
Let's be real for a second. I want to have Riot attention on this matter because i like playing big tanks and right now it's almost impossible.
Tanks were already in a bad spot by the end of season 5, and if things don't change they are in a even worse spot now.
The new AD items combined with the new ADC mecanics and masteries leave little options for tanks, and it feels bad to build tons of armor and health just to get blow up in 4 shot.
Unless you have a super good early game, you will never catch up as a tank right now.
Why do i like playing tanks? I really like to play the "engaging" tanks, those wall of meat that are super good at engaging and causing a mess in the enmy backlines. I'm talking about dudes like Zac, Sion, Sejuani, Volibear.... long time ago you could do your job as a tank allright (i'm not talking about when tanks were op), if you did the right engage you could take massive amounts of damage while setting up your team in the best way possible, but if you failed you would just die, wich is okay. As of now even if you do let's say a perfect engage with Sion there are SO MANY % health shreds, Armor shreds, Healings reductions that you will 75% of the times commit for a suicide as a tank.
Not only that but Tanks were completely eclipsed by juggernauts, because yes they can have less engaging tools but... come on.... Dudes like Darius and Garen take the same (IF NOT MORE!!!) damage then a full tank Dr.Mundo while killing off a target for half of his health. Then why having tanks in the first place.
Wanna hear a fun story? I am heavily addicted to playing rankeds to climb up in this game, and i wanted to reach Platinum by the end of the season. I mainly play Support and Top, and guess what. I like playing anks in toplane: Sion, Tahm kench, Mundo. I couldn't be impactful as i wanted, in the end i was irrelevant by the end of the game. I decided i had to start picking up the Juggernauts to be succesful in that lane to have a chance, I choose Garen as a go to pick for the toplane. End of the story? 70% winrate with Garen and got my platinum promotion. Yeah cool, im very happy about that, but it's proof of what i said.
TANKS ARE IRRELEVANT.
For this pre season i will say soemthing i like that is the Resolve mastery Tree, it's the only mastery tree where you actually have meaningful choices to do to be tanky as you want. But that's it it doesnt help too much with all the things i mentioned above.
Riot i demand justice and an answer on this topic, since it seems like you dodge this kind of questions.
