Fiddlesticks rework idea

After having spent some time talking on the forum about fiddlesticks, watching streamers like Narkuss playing fiddle, and some other players, and after having played him a lot too i tried to find some idea...

Fiddlesticks have a nice and unique skill set, he has his Terrify that is famous, his Dark Win that bounces between target, and his Crowstorm is awesome ^^

The problem of fiddlesticks is his Drain, there is no pleasure in using it.

This spell was strong at a time where people had no much interrupts. So riot games decided to nerf the spell vamp of the drain (it is 60% now level 1 i think)

But now every champion have dash and interrupts... Damages are high...

So drain is not so strong has before... you can just use it to make the crow bounces while ennemy is feared usually

I think making the drain not interruptible would solve the problem. It already has been nerfed so it just need to be uninterruptible.

Fiddle wouldn't be able to move while doing it but it would only cancel when he is too far away from the target.

Basically you will have to use ignite/anti healing item to kill him

Also his most stupid weakness is doing baron with the team: It should be his strengh: When he drains, his smite/next spell will do 125% damage when he has drained for 1 second (so he cannot steal nashor easily)

EDIT: i forgot a little problem " Baron's Gaze: Baron Nashor takes 50% reduced damage from the champion that he has most recently auto-attacked for 15 seconds. " this should not apply for the drain healing

Edit: Another idea would be to give him something like malzahar spell shield but i like this idea less
