The thing is a unique totem, like Cleansing Totem, would be way too OP in this stage of WoW, than it was in the era that it existed. The only way I could see Cleansing Totem be remade with the debuff removal, is if it would be readjusted so it doesn't become op.
Cleansing Totem
Instant 3 min CD
Summon a Water Totem. Decreases periodic damage taken by 10% and instantly removes 3 Magic
and Curse effects on 3 allies then, removes 2 more effects per ally every 5 seconds (The cleanse ticks will prioritize magic over curse).
Lasts 10 seconds.
Something akin to this would be pretty unique. The only thing is, if it's dispelling effects like VT or UA it should have some downside.
