The Tree of Savior site has been updated with a lengthy blog post about forthcoming changes to the combat system. Revisions will be targeting skill balance, summon AI, armor, PvP and boss cards by checking on "usability and balance" in particular.
The blog post goes into detail about five core areas the team is currently focused on:
1) Improving the usability and balance of skills 2) Improving summon AI 3) Increasing armor stats and readjusting PvP calculations 4) Introducing two-handed blunt weapons 5) Reviewing the boss card system
Each section above has a lengthy discussion as well as several examples of how the team is addressing each area. You can check it all out on the Tree of Savior site.
