Laning in the current meta
From what I've observed through meta, mid-laners often (not always) choose a champion that has a weak early game and strong late game (Ezreal, Veigar, Ryze) or simply a squishy (Katarina, Lux, Ahri), and the Top lane is reserved for either tanky champions, champions who can perform successful ganks, or both.
Now WHYYYYYY shouldn't these roles for lanes be switched? If a champion such as Veigar has such a weak early game, why put him in a position that allows him to be ganked from two sides? Should he not go top lane? Top lane is a solo lane just like mid lane, its got the same CS opportunity except for the travel distance I suppose, but seeing as how all minions spawn and cover ground at the same time I don't see how this is terribly significant.
If mid-lane is what matters late-game, should we not fight w/ our tanks there in early game? Harder to gank, easier to defend your mid, and your early-game-baddie can go top and have only one side to be ganked from. He can just ward that side and be good to go.
The only arguement I can think of is that if your early-game-baddie should be attempted for a gank in the top lane, it would take incredibly longer for ADC and Sup to get there. Does this really make ALL of the difference? I mean, the meta would change wouldn't it? the mid-laners traditionally have Ignite and flash; if they switch to top, they would replace ignite w/ heal, and the ADC or sup would switch one of their respective summoner spells w/ teleport. The mid tank would probably use less ignite and more barrier or heal since his/her purpose would be defending the mid-lane from disaster.
Comments? Please be nice. I'm not in ranked like many of you, I'm just sharing some thoughts.
