All of that makes sense but there are advantages and disadvantages to all the choices.

Guardian Angel is a 5 minute cooldown, still leaves you out of position if you die.

QSS doesn't provide a counter to Karthus' ult, nor generally prevent horrible death due to mistakes (we all could play better, I understand; nevertheless, we're human).

Hourglass is interesting though; it is a 90s Cooldown, 2.5s invulnerable, outta-meta choice (for marksmen), with good armor and AP. It leaves you out of position if you use it wrong, AP is a wasted stat on some marksmen. It doesn't revive and give you life, it doesn't provide cleanse-on-a-stick, but on a marksmen where AP is not a 'total waste' it might be a viable alternative as well as a 'wtf?' button.

Is it normal? Hell no but I'd love to see how it goes. I think Ezreal probably can use this without any issues.
