Another random skill / ability that i was thinking about

so.. i was playing some League.. and i thought.. Really dont know if this is functional or not, but...

how cool would it be if a champion had a large weapon almost a turret like item that they had to drag around.. it reduces their movement speed but comes with a bonus of damage or almost like a turret device effect.. they have the ability of being able to set it to self destruct and you get a nunu / team Zigg ability ..

you could use this ability to launch your allies to locations a good amount of distance..

what inspired this was looking at ryze do his TP thing.. seeing ziggs do his bounce away thing..

and than i was like .. cumbersome turret ..

what can be a benefit of this .. damage reduction from the front?
extra damage.. unique abilities when you have the turret??

dont know.. just think about launching a team the distance that a zac can jump?
i know it doesnt have to be that far.. but if it was.. come on man.. if it was.. https://c2.staticflickr.com/7/6140/5974820993_348c79657f_b.jpg
