You cannot miss your laser. You will be getting it around 20 seconds or so if you follow my core build. When you use it every 20 seconds (if you chose to) make it count. Your team depends on that laser and late game you can half all the squishy enemy's health bars. Lux is one of those champions that can use her ult as many as 2 times during a average team fight. One during and one to clean up. The more accurate you are with your laser the more you will help your team, in turn making you a more valuable team member.

Pros:
High out put all game
Heavy CC (if used correctly)
Can clean up
Can destroy weak targets with one ability
Low cool downs
A Shield that doubles up
Great Harass
Easy getaways
A freaking Laser Beam

Cons:\
Zero help to your team if you cant hit your ****
Doesn't really make a difference without mana
Needs a skilled player
