Inconsistent Alpha Strike mechanic
Just finished playing a 1v1 as Karma vs. Master Yi. When casting Focused Resolve (W tether) on Yi, if he casts alpha strike the result on the W was inconsistent.
My understanding is that the tether should persist, which it does sometimes. Most other times it would fail and refund the CD, a couple of times it would fail and go on CD.
Whether it persists or not doesn't really matter, but shouldn't it be the same every time?
