I'm not sure what you're talking about patch 7.8 changed his Q to making it viable to duel champions which he was losing on at the time. In fact they overtuned it to the point that it had to be nerfed from 40 magic damage to 30.
His dash was changed as well because with the amount of energy it was taking You'd find yourself only being able to use Q once and not twice in a fight.
Lastly his ultimate was changed to less base but added % missing health shield based on how low the shielded ally is. This nerfed him in competitive where he was an issue (people would ult early since they can talk and use it to turn fights) but buffed him in solo where a good ult can save your teammate and is mostly what people use it for.
