I think the Stun effects which some Jobs have should be reworked into a Paralyze effect (cureable trough Purify) or Bind, and Silence into only disabling specific Skills and not ALL of them.

I would also like for the Guard Skill to recieve some Buffs directly or indirectly, since there are MANY Skills that either nullify (WAR) or bypass it (like MCH, RDM and MNK) even if it would mean losing 1 or 2 sec on its duration.
