Zen Meditation
Sparring
Combat Conditioning
Energizing Brew made into a talent from baseline
Buffs (Legacy)
Grapple Weapon baseline to PvP Talent (worse version)
Disable duration decreased from 15 seconds to 8
Swift Reflexes
Tiger Strikes
Crackling Jade Lightning being a joke spell since WoD
Just to name some others yet interesting and core spells for the enjoyment of windwalker gameplay back then.
Especially a comeback of tiger strikes, swift reflexes, and Sparring could put Windwalker in an enjoyable spot again.
