New secondary runes?(coachless)
Magic footwear fixes mobility issue though you are more vulnerable early but with help from homeguards it doesn't matter
And cosmic insight is very good if you run flash+ghost so you can use them more in lane and not get statchecked by barrier every 3m(your ghost is only 20s off barrier), plus ghost outscales barrier.
I still run triple/cashback +cosmic and feels better mostly. But probably footwear is the secret cook(though the timer suggests it is played by good people that are stomping and getting them early)
Now for the lesser runes:
adaptive instead of attack speed is better for the green poke, though you may struggle with cs but a single point in W fixes anyways. Ms shard helps fix mobility issue early and compensates not having boots, also has insane synergy with magical footwear, paired with phantom dancer and ghost you are kiting king.
Smolder runs ms shard and adaptive and has not fallen to the bottom despite the massive nerfs he got. We should learn to use the better runes, this trend shows accros multiple adcs favoring ms shard and flat adaptive.
