User blog comment:Bobchen/Which lanes do you think are the most difficult?/@comment-6486964-20130621022401/@comment-4022742-20130621085035

Bot lane has a 2 vs 2 situation already, if they don't have the upper hand, they should manage not to die if they play with care. Top and Mid however get quite risky if you want to farm when your opponent is good.

Then theres the simple fact that bot lane has a dedicated ward machine that has simply no other function pre-6.

The rest is a form of math, 2v2 into 3v2 is simply stated 150% vs their 100%, power wise. Compared to top or mid, a 1v1 becomes a 2v1, or 200% vs his 100% power wise. I like the latter odds better.
