We all agreed the Assassin meta was toxic, now you complain about Tank meta?
Tanks are still the same. The jungler tanks with cinderhulk are just more powerful than before. If the team has 2 or more tanks and you have 1 or none at all, its gonna be hard to win that game. It isn't impossible. The ability to soak damage and dish out CC as a tank means nothing if you don't have teamwork. Assassin junglers/Bruisers are just as good at winning as a tank jungler. It is all about the objectives and early game pressure, who farms the most, who gets the most kills and what team can out preform the other. Some tanks right now might be a little too strong like
but that doesn't change the fact that it is Sejuani. A champion that is easy to counter jungle, has a weaker early game and is team reliant. So before everyone complains about tanks think about how you preformed and how tanks have many flaws. Being kited and focused by 4 people isn't very attractive, tanks can still melt in approximately 2.5 seconds if you focus the frontline, not the ideal target but still viable, destroy the tanks, destroy the squishies.
Edit: And lets not forget about your tank melting item options.
