Ranged Champions are ruining Top Lane: How do we fix this?

As we all know by now, ranged champions dominating top has been ruining the lane and indirectly, all of Summoner's Rift [LoL Article - On Top Of Things: Three Strange Top Laners In China]

• It's the reason why Shen, Garen, Darius, etc. are never seen anymore.
• It's the reason why assassins are running wild and fill 5/6 ban picks every game.
• It's the reason why burst damage is king, and Youmuu's and Zhonya's are necessities every game.

There's nothing that's become more cancerous than some Diamond deciding to try Vayne top lane, and now its become a malignant tumor. Poke comps are dead. Teamfight AoE comps are dead. The only strategy that exists is burst or be bursted, with Zeds and Fizzes skulking in bushes just waiting for you to bend over.

So since we know the issue G&B, how do we fix this and get our front line back?

I was thinking of creating another Doran's item, similar to .

Doran's Guard (Melee only) +10 Armor UNIQUE Passive: Every time a minion is killed, produces a 40 health shield that blocks ranged single target attacks from champions. If shield is broken does 20 damage to attacker.

This may be OP as hell, but the point is to discourage ranged auto-attack harass when melee champs go in to last hit. The shield is produced when last hitting so we won't have to worry about Thresh abusing the item bot lane. It only blocks ranged autos so it's not useful against other melee champs. It won't block spells so mid lane Mages won't be affected too much. Something like this will lure champs like Sion and Nasus back to top, which means a melee champ is necessary as a counter. Let me know what you think!
