Some buggy things.
W to a location. Mimic the W. Teleport back to 1st W. Teleport to 2nd mimicked W. Now Mimic isn't locked onto any spell, when in fact it should still be locked onto Distortion.
Bug 2 (Visual)
W to a location. Teleport back. Mimic the W. Now observe that the ability icon has the circulating line around the regular W, when it should be around the mimicked W.
Also, the delay on W feels really bad.
