There is a dragoon in the static I am in and he happily uses jump through out the entire fight. It feels a bit weird watching the links jumping up and down with him.

He only picks up the debuff if he is too slow when the add phase starts or he accidentally steps in to the field. And I can tell you this with confidence since I am one of the people who is doing call outs and making sure everyone is healed and buffed accordingly if they pick up and stacks.
