Is the new Lux buff misplaced ?
If you wanted to actually buff Lux, was it really a good idea to put this cooldown refund on her ultimate ? Instead of, I don't know, an help to her waveclear ability ? Like giving her E a Gragas Q treatment, for example ? A bit less damage on instant pop but more damage if you keep it on the ground ? Over a whole combo, you could keep the same damage, as you could pop the E at the end of the Q snare, and you could then maybe reduce the mana cost on it since, not as strong and unfair as a poking tool since less damage on instant pop. It would also help her greatly against those unfavorable matchup as you actually need to be ahead to clean caster minions with your E instantly where most mages nowaday are able to do the same thing but with their low cooldown/low-mid mana hungry spells ?
Has to auto minions to clear
Has to auto minions to get mana back
While he can clear perfectly fine without autos and isn't as mana-hungry as Xerath, his ranges are generally less than the other two so he tends to be closer to the action anyways.
Truthfully I don't entirely consider him an artillery mage like the other 3. I know he IS but he honestly feels more like the upper tier of the mid-range mages rather than joining the other 3 above at the high-range mages.
