A lot of things that made the classes fun and unique is being removed and already has. It's sad, really.
Even silly spells like Eye of the Best and Sentry Totem was just fun to have, and make your class special.
I guess those times are over.
Auras and Paladins aren't really synonymous in Warcraft though. Maybe it was in D2, but Auras were hero-wide in Warcraft 3. Trueshot, Thorns, Endurance, Unholy, Brilliance... If there were anything I missed it was that element of providing buffs for allies. I thought they would have done that more with different classes/specs in Warcraft. It would've been nice to have a Frost Mage bring in a Cooldown reduction aura, while Fire brings in a Spell Crit aura. But with homogenization, who really cares about being a special snowflake any more.
They're going in the opposite direction I want them to go, but at least the game's balanced :/
