Karthus can win mid lane if top/bot is winning and other is doing well enough, as jungler doesn't need to be as active there, also if jungle is winning hugely Karthus can get all of own team blue's and dominate mid. This is also true in not blue needing junglers (Lee Sin, Mundo, etc...), and even if the jungle is a mana eater, BoS or map awareness can make Karthus' 3rd and 4th blues possible (maybe even 2nd).

AP mid ganking isn't really super important at current meta, and Karthus can support ganks by Requiem (especially if he gets dem blues), when also helping a possible 1v1 push-out/lane kill on the lane not being ganked, sometimes even mid, as in laning phase that is propably more useful than taking one guy down from turret, wasting ~1000 dmg on rest of the team.

Countering Karthus is propably his largest weakness, if Karthus can be forced to harass his mana down, or just be out harassed he will suck late game, and might not finish Raba's before enemies have enough MR to not be super afraid of AP.
