Why is Lux not allowed to have waveclear?
Usually people pull of an argument „ But Lux is long range, having a waveclear would break her”, meanwhile Anivia, Xerath, Ziggs, hell even Velkoz have comparable ranges, and they are allowed to nuke minion waves like nothing in one combo. Meanwhile Lux options are either use two e's missing some minions in the process, and burning a lot of mana, or throw e and then go basic attack everything like an idiot, which will also in many match ups get you killed.
I made this suggestion before, and I will try again. For one, make Lux E projectile have a slower travel speed to give enemies more time to react to it and dodge, I think thats the part about laning vs Lux people hate the most, the E is just too damn fast. Now that E, actually has a counterplay vs champions, buff it's waveclear, make E do bonus damage or apply and proc her passive instantly on MINIONS ONLY. Then you might actually see Lux at worlds, or give her a chance to be a competitive pick, instead of giving her irrelevant buffs that can be reverted for all I care, because they solve nothing.
