That's true. She is a lot harder to play as a support in return, though. Where sustaining/healing champs like Soraka and Sona are reactive support and let the carry do as they please, just giving backup, Lux is very much a proactive support. Most of her abilities involve strongly encouraging your partner to do something, whether that's snaring someone with Q or shielding your ally when they're close to encourage them to poke a little harder without fear of reprecussion.
