Design Philosophy – New Trainable Abilities

Design Philosophy – New Trainable Abilities   At the release of The Burning Crusade, each class was able to train 5 new abilities (with the exception of the warrior only receiving 4). Generally this would be at even numbered levels above level 60, but not always (paladins getting lower level spells for example).   Fast forward to the upcoming WOTLK, is there a design idea of how many spells are going to be added for each class. Are the class designers looking for numerical parity (as was almost perfectly achieved in TBC) or just adding spells as needed for each class.   A blue comment on this would be interesting.   At the moment from what I can tell (from WoWhead’s WOTLK database), the new spells and their trainable levels are:   Druid Revive (12) Savage Roar (75) Nourish (80)   Hunter Bear Trap (75) Kill Shot (80)   Mage Frostfire Bolt (75)   Paladin Sacred Shield (80) Shield of Righteousness (75) Divine Plea (71)   Priest Divine Hymn (80) Mind Sear (75)   Rogue Fan of Knives (80) Dismantle (75)   Shaman Hex (80) Lava Burst (75)   Warlock Demonic
