Arc Thrower change in 4.1.1

Unless I somehow missed this during the Into the Unjust: 4.1.0 Patch, this Tuesday's patch of 4.1.1 seems to let the Arc Thrower stun and thus stun lock a War Strider so that it can no longer attack you with any of his weapons, main canon nor its grenade launcher. I can't tell if this is an intended or an accidental change, but I figured I'd share the wealth of this knowledge with others.

Please let me know if this actually happened in 4.1.0 and I've been sleeping on that ever since, but I swear I hadn't notice it until 4.1.1.
