Could Lux maybe call her shield back early?
Her W is really not a very good skill, i guess we can all agree on this, but i guess thats because all her other abilities are so strong, and I am really fine with it, but maybe she could get a little QAL buff that allows her to call back her shield early if she presses the buttong again, in case you only want to shield yourself?
Pretty please https://media.giphy.com/media/V3TtZ4IWyVZgk/giphy.gif
