#hp spells

I do not understand why people tell Harry that Expelliarmus is stupid. Like, last time I checked, they can’t perform any (good) magic without their wands?? Voldemort can’t kill Harry without his wand, so isn’t it just logical to take the wand away from him? Why does everyone just disregard the spell that makes your opponent useless? Getting rid of the wand is the most logical idea, Harry, don’t listen to everyone else.

I feel like whatever witch or wizard invented the spell Accio was one that contastly had a sleeping cat on they’re lap cuz honestly I feel the need for that spell everyday
