Where the IGLs have to be mechanically good. Ange1, Boaster, Saadhak, Kingg, Staxx all the top IGLs minus FNS are really solid mechanically. FNS is the exception but aside from the last game even he has been looking better aim wise
Ange1 has trash positioning and he overpeeks 24/7 but his aim and crosshair placement are good, you watch angel POV and see that he's clearly much better than someone like fns or dephh.
Good strats can put your team at an advantage, but to convert that advantage you need to have solid mechanics. Boaster and Ange1 improved their aim in the off-season a lot.
I remember in 2021 Boaster's aim is not even mid but bad, really bad to the point where fans are calling for him to be dropped, but he started to improve steadily & eventually have the firepower that he once lacked
