Bruiser/Sustained Top
Ability Power Mid
Support/AD Ranged Bot
Jungler/Initiator
That's all you get, do it or else you're ridiculed for having a less than 'ideal' set up. Sure, you can get away with changes like swapping the AD Ranged and AP Mid but that's about it. Sometimes I wonder if the meta actually only exists because the pros and game designers say it exists. Why not just throw your AP up top with a support, forget the jungler and have a ranged AD in mid then a kill lane bot with two damage dealing champions? What's stopping anyone from doing that? Imagine if you didn't have to worry about playing a specific type of champion in a certain lane.
The meta game, or just the sole fact that a pretend meta game exists, is really getting to me. I've been playing this game since beta, maybe not as frequently as most people, but I've been around it long enough to watch it grow and evolve into what it is today. A mass marketed, you-have-to-play-it-this-way game. I feel so bad for the champion designers because the current meta prevents truly unique champion design. If a champion cannot fit into any of those roles, they are ultimately destined to be doomed and unplayable in competitive play. (Which isn't a good design philosophy)
I have other lesser problems I'm running into as I figure more and more out about how the games played. Unfortunately I doubt they're ever going to change them now. The design of having two different forms of damage that can be modified and damage increased through items is annoying. Maybe not game breaking, but annoying. Items should be there to compliant your champions tool-set, not steroid it. If Riot focused more on balancing the champion's tool sets against each other and creating smarter counters that lasted through the entire match, the game would be much more fun. But the "existing" meta game prevents that.
All I want is for the game to be more flexible with it's meta. Why should there have to be a set guide telling you what type of champions you can play? The meta should allow any kind of champion to counter any kind of champion. When a team picks an AP champion for their mid you shouldn't have to look at your available champions and be forced to pick another AP champion for their AP champion in the middle lane. You should be able to look at all the types of champions you own and pick any that can counter that champion and go into that lane with that champion.
Why does the meta even exist? The huge population of players need to stop acting like sheep and doing only what the pros say to do.
