Very useful to counter slow pace attacker
I think even though interceptor seems like an op ability its very easy to counter as it has a very long cooldown (45 sec) so you have to be thoughtful about how to use it. Anyone above gold can work around the ability as it makes very loud noise so you can rotate accordinly. Also the ability itself does not last very long and its very breakable. The only reason people will insta lock him is due to the ult and still you can at best use it 2 times in a half as people in ranked hate to use their ultimates.
