As previously mentioned and as a part of the rollout for level 51+ abilities, all skills now have a movement cost associated with them. (Ki and Spell abilities are unchanged.)
You can expect to see the each class' 2 class-specific universal skills for 51+ plus soon. Profession-specific classes for each class will follow.
Your practice list and the "skills" command should both show the associated costs. (Some skills affecting a full group may have a per-person affected cost associated with them.)
Direct questions to Apoc and please post any issues in the forum.
Thanks!
