Comparing Lux with Xerath
I love playing Lux - she's one of my favorite champions. But I've recently gone against a lot of Xeraths in lane, and it leaves me fuming. It seems that he can do just about everything I can do, but better. I love the archetype of a long range poke caster, and it seems that Xerath and Lux fill that class in different ways. However, with the state Lux is in now, I'm not sure if there's any reason at all to pick Lux over Xerath.
Granted, ability comparison doesn't show everything, but here's some interesting facts.
Xerath has a bigger slow, harder cc, longer range ult with higher damage, better mana costs, cheaper and better poke, longer ranged abilities, and more reliable waveclear. Lux does have a two-target bind, but I think a single-target stun is still better. Lux also grants vision, and has a shield.
Xerath feels like artillery, while Lux feels more like a kitey scout sort of champ. I don't think that they should have homogeneous abilities. But I think Lux needs some changes to make her shine in her own role, and not just get outclassed by Xerath in pretty much everything.
**TL:DR Lux and Xerath have similar but distinct roles. However, Xerath performs better at most aspects of Lux's role currently. Changes need to happen to make the champs more distinct. **
