They should give both platforms iOS and Android the same attention by using Vulkan on Android and Metal 2 on iOS and utilizing most of if not all the smartphones capabilities so they will be able to push the graphics to its limits and maintaining stable performance at the same time. Graphics and performance, they should learn from their mistakes in Asphalt 9 and all the previous Modern Combat games, not to put all their efforts on optimizing it to run as best as possible only on iOS.
If Gameloft wants to move the series to the next level this is what they should do: I am not talking about modern combat spin-off (versus), I am talking about MC5 sequel that we all hope to see it come out.
