I don't know every class's previous powers and which class lost what but the somewhat recent changes to Warlock Soulweaver removing Killing Flames as an Encounter Power option effectively pigeon-holing a Soulweaver to have very little damage output is confusing.
Oathkeeper (Paladins) have Smite with a whopping 900 magnitude and Bane 480 magnitude.
Devout (Clerics) have Geas 500 magnitude (albeit with a long cooldown).
Killing Flames had it's magnitude increased to 500-750 magnitude but is now only for Hellbringer.
Why such drastic measures?
