Champion Concept: The Mirror Master

Hey guys, i just had an idea for a champion kicking around in my skull for a bit and i decided i wanted to share it with all of you :D. I don't have a name or backstory for him/her yet, but I do have a pretty interesting skill setup.

Passive: (can't think of a name)- Any attacks that are reflected by Mirrors gain 10% damage, stacking up to two times.

Q: Mirrors- ??? spawns a mirror in target location facing in a direction of his choosing. these mirrors interact with his other skills.

W: Glare- ??? shoots a beam of light in a target direction. Champions hit by the beam are blinded for 2 seconds. Champions hit by a beam reflected off of a mirror are instead stunned for 2 seconds.

E: Reflection- ??? spawns a different mirror in front of him lasting 1 second. This mirror reflects one skillshot, returning it on the same trajectory, applying half damage and any CC effect with half the duration. Any skillshot reflected off of this can be reflected off of Mirrors.

R: Connecting mirrors- Two of ???'s mirrors become connected for 2.5 seconds, allowing for travel between them. Any ally may walk into one mirror and come out through the second one. This champion is a support/mid/top laner. ??? is a high utility, low damage output champion that can be increased slightly with good positioning on his mirrors. He can set up some very interesting plays with his ultimate, allowing for ambushes in unexpected places, low risk dragon/baron steals by allowing the jungler to walk in and out of pits easily, and great escapes from bad situations. However, coupled with that is its low range and the fact it takes a couple seconds to set up his mirror network. I would almost be tempted to say his E is overpowered, but when compared to things like Yasuo's windwall or Braum's shield, the fact that it can only block one skill I feel balances it out. If you have any comments, questions or concerns i would love to hear feedback :)
