The follow up skill of Mesmer's Mantra of Concentration, "Power Break" previously broke stun. With the new system, this skill no longer breaks stun. This may be a bug or a feature, but the description says "Chant the mantra of concentration, breaking stuns on yourself while granting stability to nearby allies." I would assume this means the skill should break stuns for the Mesmer, and is likely a bug.
