which 61-70 researchable spells have no upgrade?

[Taaxi]

I'm looking for spells that have no better version, like Champion for Shamen and Sha's Legacy for Beastlords. What are other spells are there like that?

[Bobaten]

Slow applies to the other 2 classes as well (Desolate Deeds, Balance of Discord). Others I can think of are Guard of the Earth, Oaken Vigor/Blessing of Oak.

Shammy haste never got updated after Swift like the wind / talisman of celerity did it?

You'll have to doublecheck me on these -

Talisman of Might (sham 70)
Talisman of Sense (sham 68)
Talisman of Celerity (sham 64)
Talisman of the Diaku (sham 64)

[Bobaten]

Might and Sense have an upgrade (Foresight that autocasts Mammoth). Oh, and Talisman of Celerity is now called Talisman of Alacrity(but you are right that there is no upgrade). Also add Feral Form and Feral Pack to the list.

Night Stalker

the necro gimp group heal, night stalker, doesn't have an upgrade
