Seriously riot.. it's been in for way too long.. If you're stunned you're stunned. IT means you cannot take, or continue any actions except under extreme examples.
There is literally zero excuse to allow garen to continue to spin while stunned...
Because his spin is not a channel.
Same reason why wukong’s ult isn’t stopped by CC.
Except that there is a reason for keeping it like it is: Garen has been balanced around this feature.
I hope you do realise that if his E could be interrupted by Stuns, then they would most probably buff Garen by a lot and he pretty much would be busted vs any laners that don't have a Stun in kit or ways to kite him. Basically, most melee champions would be bullied by him considering he can also silence them.
Same reason Swain can keep ulting or tristana can complete her jump.
