A tweek to Bards ultimate

As someone who actually plays Bard, even in ranked, where I played +20 games with him and maintain a +50% win rate (woohoo), I would like to see the following 2 tweeks to his ultimate.

Firstly I would like to see his ult have a visual indicator of when it's going to run out. Now the reason for this is mainly, because when you ult someone, say like their marksman or mid and your team closes in for the kill and you close in to land your Q and stun, that enemy that you ultied is spamming his flash or escape key and will use it almost as soon as your ultimate wears off. So you have to fire your Q at a very precise moment for it to travel and stun, just as your ultimate is over. It would be really nice, if when you fire off your ultimate and it turns people gold, that as its timer runs out people would turn back to their normal color from the head down or feet up. So you could visually see when it's going to run out and get ready to stun. I would even take the buff a bit further and allow you to use your Q on people who you ultied. It would do no damage, but it would still slow/stun, however you would of course lose time on your slow/stun, while the guy is ultied, so it would only make sense to try and stun in the last moments of your ult.

The second one is simpler. It might already be the case, but it's very situational, so I'm really not a 100% sure. When one of your enemies is attacking a turret along with a few minions, you can use your ultimate on those minions and if you get them all, the turret will target the enemy champion, who will take a turret shot or even 2, if he's slow. Now, if someone on your team then swoops in and gets a kill, I think Bard should get an assist, since he made the turret target the enemy champion and so he basically did that damage to the enemy champion.
