I wouldn't count lux as a support if
Her only support ability increases by 15 per level and has a 0.2 ap ratio. Or, if you wanna call it 30 per level and 0.4 ap ratio, that's fine. 90% of the time you will only hit once, but either way it proves my point that her shield is weak.
to spread alot of aoe slows to the enemy team.
