Shelly Rework Idea

I hear Riot is struggling to figure out how to make the top of the map relevant again after the dragons underwent an overhaul that practically made them the focus of the entire game. I got an idea I wouldn't mind bouncing around the boards.

What if Rift Herald was controllable?

Instead of mindlessly ramming any turrets in sight in a straight line, what if you could ride and control Rift Herald how you want? Use Shelly to gank a lane that's behind and kill a fed enemy in attempt to even the playing field. Use it to try to compensate for a numbers disadvantage when fighting over Dragon. Maybe give it a "Kamikaze" option, where it just rams through everything in it's path, exploding on contact with a turret. Hell, maybe even give players the option to "consume" Shelly for a big EXP / Level boost.

I could see this implemented one of two ways.
1.) Every attack / skill is available, and selectable, like a regular champion's abilities / skills (eg. - Q is an attack, W is the "Kamikaze", E is to "consume", etc.)

1.5) You could make it so certain attacks / skills become unavailable after a certain amount of health has been lost. Either that, or the power / boost is dependent on HP. For example, "consuming" a full HP Shelly would give you the maximum EXP / Level boost, while "consuming" a 1/4 HP Shelly would give you a quarter of the boost.

2.) Rift Herald skills are dependent on which Jungle item is being used. This one I think would cause a lot of problems, because certain Junglers have to run certain jungle items, and you wouldn't really be able to choose how you want to use Shelly. LIke, if your character has to run Cinderhulk, and the Shelly skill you want was tied to Bloodrazor, that would kind of suck.
