Is Lux's ultimate used to wave clear?
There is a video on LoLKing about how Lux got one of the highest win rates in this current patch and I read that one of her pros is that she can wave-clear very well. I have mixed feelings about that but I'll explain later why. In the video it was mentioned that her ultimate is used to waveclear. I know that with a bit of CDR she gets around 40 seconds cd on that thing and that it deals a lot of damage but is it really worth it? In case you want to farm just use E, Q and auto attacks, it's not as strong when you try to shove the lane and get an objective because it actually lacks damage if you are not ahead and don't have Luden's Echo, and this only clears the caster minions in one shot. To be honest this is why I do not think her wave clear is good when she must do it fast, it requires 2 E's to clear and if you have another laner (especially ADC's) with you they will generally get all the farm. Not just that but if you use your ultimate to wave clear the enemies might engage or your allies might engage not knowing they shouldn't.
In conclusion, was I clearing waves wrong all this time? Is her ultimate expendable just to wave clear?
you can't waveclear from global range, but her ult is on about the same CD as his. So it's entirely up to you.
