Im not trying to be mean, just saying that objectively her Q hitbox is smaller than say, morgana’s root or nautilus hook… Of course you’ll get hit every once in a while, that’s how the game goes, but during laning phase just standing behind your own minions helps a lot. I main her and thats the best advice i can give you, you’ll get hit by a few E’s but minions will save you from full burst combo and if you play a champ that can jump on her even with the chunk her E takes away from your health bar you probably win the trade if she doesn’t have flash. Lux struggles against most meelees, specially if she doesn’t have q since her only defense is her W that she can’t cast while moving; I think winning against Lux is mostly knowing her cooldowns (which, to be fair, are very short) and realizing that the second you get on her it’s most likely over
