Battle System for Bloodstorm

[Bourne_Endeavor]

This means we won't share cleric stance anymore ? Sch/ast will have their own " CS", i wonder what's gonna be

Not quite. They are essentially doing away with the cross skill system. Every ability there now will be available for each role regardless of whether the corresponding job is leveled. So you do not need to unlock or even level Conjurer or Gladiator to access Cleric Stance or Provoke, respectively. Both will be available from the onset.
