Orianna and her sphere of influence with her orb.

Orianna the female robot of summoners rift we know her for being one of the champions that can pull off some crazy team combos with her ultimate. However i feel that in her current state that can be harder then maybe intended. What i mean by that is Orianna can only get so far away from her orb before it returns to her, or sometimes for likely, her orb can only be moved so far away from her. This can is easily thought about when trying to combo large CC abilities. Lets say with a Malphite ultimate. An ultimate like Malphite's requires a champion to dive into the enemy team, and lets say a Malphite shielded by an Oriana does this. If the Orianna is able to stay in range everyone hit by the Malphite ult will be followed up with an instant Orianna ult, causing great devistation and generally an overall win for that fight. However staying in range with abilities like that sometimes Isn't the easiest, sometimes the malphite dash will leave Orianna's sphere of influence causing the orb to return to her. So i suggest that while a friendly unit is shielded by Orianna that they can see her sphere of influence indicating how far they can get away from her before the orb returns to her.

Any thoughts?
