Grounding totem mechanics

[farrsa]

Hey, I'm wondering about grounding totem mechanics in this game build. As far as I remember, in tbc grounding totems were destroyed upon catching a spell (even a non direct dmg one, like a dot or CC). But here these non damage spells don't kill the totem, just turn off its aura for 10 seconds.

Is this actually how it was in this vanilla build? Did it get changed only in tbc, or in some later classic patch?
