Passive being an execute being an execute prevents it from being too strong when used solely for resets. You should however have lowered the target's health by a bit before going in on them though. Resetting ult will change, like you said triple casting it is nasty. While it was meant to be her escape after going in, denying her that will make using the passive a lot more risky.

W might be a misconception, the range listed is meant as the length of the beams, which I originally had written out in the description. My bad.

E does care rather much about glyph placement though, as it is easier to hit the closer they are. Making the range centered on the glyphs would drastically increase her range (up to 2300), which gives a lot of zoning potential. Although with the delay increase at that range I could probably allow it with a few tweaks.

R has a large delay already (2.5 times as long as Leona's ult), but you're right in that it's too big. Will make it a sweet spot for the stun. Reactivating R doesn't stun though, as it cancels the channel.

As for assassination potential, it's mostly tied to the execute and reset of her passive.
