Some basic tweaks to abilities will not cut it for this champion, so Riot are, instead, implementing a never-before-seen CGU, that is a Comprehensive Gameplay Update.
On his reveal, Aurelion Sol was one of the champions with the highest purchase rate to date. However, after a few days of trying out the champion, due to his peculiar kit, it was left behind in the dust.
Though he still comes up in the top ten most liked visuals whenever Riot do champion surveys, his gameplay always ends up near the very bottom of the list.
To remedy this, Riot are giving Aurelion Sol a Comprehensive Gameplay Update or CGU.
The goal of a CGU is to update gameplay for two types of champions: Those that have a high-quality art and narrative, but whose gameplay just doesn’t quite deliver, or champions with more complicated gameplay issues that can’t be solved by changing one or two abilities.
Then comes the rebuilding of the champion’s kit from scratch with the same model, theme, and narrative. Aurelion Sol will be the first champion to go through a CGU, and, the developers say if the players are happy with the results they may take a look at other champions that fall into these categories in the future.
The champion will take a route to embody his dragon aspect more than it has until now, as he hasn't done so at all with the current kit. The release itself is scheduled some time at the end of the year, according to the developers, though that is prone to change.
