Bard Clarifications

A new champion has been released (Wooo!). The boards are already flooded with complaints of how he will be op, or how he will be a troll pick.

I think speculation/complaints on how broken a champion is going to be are not very productive. That being said, I would like to be able to think about how he might be able to be played. I always have fun doing that with new champs.

I have a few questions of how some of is abilities work. I realize I could wait until he hits PBE, but I thought I'd ask now anyway.

Passive: It was stated in the comments that chimes are semi-random spawning. Can we see them through the fog, or do we have to randomly stroll upon them?

Q: Looks awesome, can't wait.

W: I feel like to get an understanding of this, knowing its cooldown/how long they last would be pretty important. Do i have to sit in lane for 3 min to give my adc enough of these to feel comfortable roaming? Also, can I use these, or are they just for allied champions? I feel like this is a really important distinction in enabling him to be played anywhere but as a support.

E: Cool ability, this is one I think I will have to wait and see to get a feel for it..

R: If someone is already zhona's'd when this goes off, does the zhona's prevent the R or does the R persist past the zhonas?

if anyone else has any quirky interactions that they are curious about with this guy, I'd like to hear them for my own curiosity.

Can't wait to get a chance to play around with this guy. Looks like a lot of fun.
