Why solo top?

[quote=Wilio]I'm still new the whole strategy aspect of the game, but I do know that the usual strategy is to have one top, one mid, two bottom and one jungler. My question is : why does the solo lane always have to be the top one, why can't it be the bottom one?[/quote]

[quote=caucheka]because having 2 people on bottom gives better control over dragon, one person can go help jungler kill dragon and leave the lane secure because theres someone else there.[/quote]

[quote=Luther3000]Early game dragon control. Also, kewl avatar. <3[/quote]

[quote=GrimmFate]^^ What these other two people said.[/quote]

[quote=DuffTime]Because that way DuffTime can solo top. (And maybe that stuff about Dragons and junk I guess :/)[/quote]

[quote=Wilio]Thanks all.[/quote]
