LUX: It is time for a Change! Ideas and suggestions
PROBLEM 
This discussion aims to be set on Lux's passive, Illumination.
I once played Lux years ago and she has been one of my most favorite champions to embody on the rift ever since; indeed, her safe kit and back positioning suit my play style the most. Hovewer I get particularly frustrated as she is now outclassed or matched in all the reasons for which she is picked:
- range in rare cases
- damage
- safety
- wave clear (Lucent Singularity (E) too mana consuming, cooldown too high)
Riot, you always talk about** reinforcing Champions' identities and quirks** and also, making their weaknesses more evident. In this case Lux has been forgotten for sure. However one manner of solving that is reworking her passive. As the time passes on the rift, her passive is hardly used as it gets Lux into** lethal situations** which she wants to avoid; Illumination which offends Lux's range mage nature becomes useless.
IDEAS and SUGGESTIONS 
- Reduce Lucent Singularity (E) cooldown and mana for wave clear purposes.
- Reduce Lux's spells damage. In return, modify Illumination to apply more damage on the next spell she lands on a single target. Illumination could explode to apply even more damage (or true damage? or according to ennemy maximum health? bearing in mind that Lux is weak against tanky compositions) when 3 spells connect in a short amount of time on a single target (combo A+E+R).
It would:
- Attribute a new skill curve to Lux.
- Punish wrong setups and manipulations. Only skillshot weakness becomes more obvious.
- Reward Lux players who hit their spells in the neatest way. Fair damage under condition.
I genuinely hope this suggestion is worthy of your attention. For Lux's sake.
or something?
Her E? On only a 10 second cooldown?
Her E? With the slow attached?
