Rakan loses basic attack range during his ultimate

I know the video doesn't show it too well, but you can just load up into Practice Tool if you don't believe me. :P

I'm assuming this is intentional, as if you accidentally attack move or click on an enemy champion, you wouldn't be in range to charm them with your full 300 attack range (it lowers to 50). However, if for whatever reason you decide to do an on-hit or full AD Rakan build, this would be important to know (I don't recommend it, but I'm sure someone has tried). Just a little note in the tooltip would be greatly appreciated! If you press R while autoing someone, you automatically move into your new attack range.

Also, can we have some sort of indicator as to how long his ultimate has remaining? There's no buff for either team, as there would be for, say, a Singed ult. You have to count to 4 seconds, and if an enemy Rakan begins his ultimate outside of your vision, you have no idea how long he has left on it.
