Lux is a burst mage and Lich Bane is best suited for a dps mage. That and the range argument indeed.

Also, at everyone saying Havoc is a trap: I would prefer 2% damage on my complete combo ON CHAMPIONS than +4 damage on each minion attack I deal (that actually is only a 5% increase as well)

Yeah-no.

If you're getting close enough to autoattack with Lux, you're doing something wrong - i.e you're getting too close to autoattack.

Lich bane clarity and clairvoyance are all unviable for lux I have been advised about the summoners when I made my guide and lich bane puts you too close to the teamfight, you might as well not play lux if you play her as an up close and personal mage since her kit emphasizes long range. Additionally summoners insight is pretty much a necessity and havoc is garbage, also in the cons section you said she is a bit weaker late game than early-mid, Lux is really strong late game since you will be shooting off 1000 damage lasers every 30 secs and has 2 strong high damage abilties that can hit multiple target and can be used 2 times in the space of a fight.

A bit more description for the runes, masteries (you even admit that wanderer is insignificant and yet only say maybe get the reduced CD on flash) and items as well as situational items would be good the guide is also kinda short and could be more in depth overall downvote from me.

Still pretty new to the whole greating guide thingy.. so all the fanzy things that others do.. cant do that.. haha. Im trying to learn! :D

Thanks for your comment, and your opinion is your opinion, Lich bane on lux is awesome. Will correct the errors tho.

Try to make your guide more beautiful, The essence of success is have an attractive guide.

You put points in the utility tree and completely forgot Summoner's Insight .
Havoc is a trap.

Lux should NEVER get Lich Bane late game - she should not be close enough to use its proc.

Clarity is never viable.

Several spelling and grammatical errors.
