In terms of Warrior skills not that much needed changing since 1) Changes have previously been made and 2) they already have a great array of abilities. Anything they are lacking is more a nature of their class. There's no point adding a new Flaming Sword (for example) because any new power increases will come the current skills reaching level 4.
You have to consider - For example level 4 Twin Drake Blade + level 4 Twin Drake Fire or level 4 Flaming Sword + level 4 FlameswordFire. These combinations would trash most of the updates to Wizard / Taoist skills.
Furthermore "updates" to Wizard and Taoists are not necessarily in their favour, for example greater MP consumption and Shield dropping faster based on your attacks.
It is anticipated that the spell "Awakened" will be adjusted in a later update to give greater regen but that will involve the removal of Redemption so for the time being we will see how things evolve.
Diamond Skin performed better than we expected in testing however if upon review in the active game environment it is still disappointing then that will of course be addressed. It also has an impact on a
possible future skill which if dropped from development, might allow changes to be made.
Play first, flame later
