Role Overload

tl;dr I'd like a balanced team to fight against, not a tank-n'-fighter-n'-sustainability fest

Fighter tanks with incredible sustain are difficult and unfun to play against. Champions with cheap/straightforward abilities and high damage output are demons. Champions that you can't touch because of their abilities are just plain awful to be paired up against.

I'm okay with taking one of each of them. But imagine playing a game where you have to deal with multiple champs of the same type listed here. I understand that there are times when team composition just happens to be what determines a winner, but when you are pitted against three tanky fighters with tons of sustain or three champions with extreme utility and CC or a Heim and Singed playing Hot Potato with you and Heim's turrets, it's a little hard to actually try winning the game when you keep dying from dives that don't do anything to tanks, multiple stuns and slows, and flings.

There's synergy and then there's extreme cumulative cheese on the same team. Wouldn't it be better if we could prevent a Mundo, Nasus, and Volibear from wrecking face or a Fizz, Annie, and Brand from melting your face off just because they can? Having to deal with multiple champions of the same niche doesn't make for a fun, dynamic game--it makes for games where you can't go outside of the base because you'll get caught by burst damage or you can't fight anyone because they're tanks. There's 123 champions to play in this game and there's always the chance you'll fight the same kind in three different forms. And that's never fun. There's a possibility of making people have to play a role so that the team is balanced out in composition--e.g. tank, fighter, support, another fighter, and a mage--so that we wouldn't have to face the horror of going up against three Juggernauts. I feel like we had that ability before... Oh well.
