which mage pet to use in a necro mage duo

[Daldaen]

Water pet does more damage and has more health than air pet.

I am personally of the opinion air pets suck during classic. Later on in EQ when they could stun mobs higher level than themselves with high frequency they were the best tanks. But currently their stuns are low duration and seem to resist a lot. To the point that I don't notice the stun much at all.
