Having checked the spell lists I've noticed some things.
HotR works with weapon damage and not DPS.
Divine Protection works as a Shield Block.
GAnK acts as a Shield Wall.
Blinding Shield and Shield of Righteousness are (or were) MIA.
That got me thinking.
Neither Holy Shield or Avengers Shield need to require Shields. And Blizzard do want to differentiate Warrior and Paladin tanking.
So....
What do Paladins feel about the possibility of tanking using a 2H weapon? Pure speculation and not interested in mechanics or the possibility it'd make DKs and Paladins too alike instead.
Just...if Blizzard put in suitable mechanics to replace the shield, would you like the change?
