Hymn of valor way too cheese
I don't know/remember most of her changes over the times, mostly because it seems the developers are never satisfied and are always tweaking her, but I think that there is 1 thing that should definitely change, and that's her hymn of valor(q) range.
it's not a skillshot, hell it's not even a click to win spell, it's just a push your button and grin spell with 850 range, meaning with absolutely no skill she can level 1 zone all adc's away while still being very safe from their auto attacks.
no aiming, no concern it might hit a minion, no need to click a target, no need to even be close to a target...
Like I said, I don't know how her kit got to where it is but I do know what I'd like changed.
her damage is not overpowered if she actually had to try for it, so I say reduce her q range to around 675-700 and buff it's damage to something like 210/210+55% Ap up from 200+50% Ap, or give the "on next hit" damage a buff to compensate.
