specs?

prot/retri paladin main + ele/resto shammy alt would be my advice.

Depending on what content you want to do to level.


Prot+Resto would be good for instances.
Prot+Ele would be good for duo'ing elites and group quests.
Retri+Ele would be good to grind through normal quests.
Retri+resto, wouldn't be very good. Mana management mainly, you'd have a lot of downtime with this combo.

In any case, it's always best to main the melee and alt the caster/ranged.
