Ha! I predicted pretty much exactly this, the Paladin quest had to be related to buffing your minions. Now I sure hope there is some more support for this. Perhaps a 1-mana spell that Adapts a friendly minion?
Seal of Champions will roatate so we are left with Blessing of Might, Blessing of Kings, Silvermoon Portal and Blessed Champion (only the viable ones). Also we're hoping for new buff spells (Dinosize and more). Overall okay, though I think it'll take some time to finish the quest.
