The buffs on his Scorcher makes his laning phase way better. If you put points into it he basically becomes a 1v1 monster in lane. Probably the best top laner right now since his build path was never reliant on Crown (there is a build where you just go to AS immediately at the start that’s been going around). If you play him in top, you will 100% win a 1v1 and can still win if their jungler supports their bot (assuming you’re that good).
Other than that, the buffs on his ult makes gap-closing and counter-engages so easy as well as escapes. There is virtually no time to dodge his C effects as a squishy carry anymore unless you have a dash. The damage he puts out just after his Aftershock spike (6-8min as top) is incredible.
At the same time, I think he’s one of those heroes who’s rewarding for players with great mechanics, who are able to dance around the fight and get onto key targets without getting locked down and just weaving in out of teamfights. Players who can’t execute are apparent compared to the ones who can, so I don’t think he’s overpowered to the point that literally anyone can play him well.
