The faq on here for Dragons Flight seems to rule that shifting in combat is not classed as moving:

Does this mean shifting in combat to 50/50 or 100% position against the defenders tray when attacking would not allow you to pick up or claim objectives if you touched or covered a token (as determined by the specific rules in that mission) as you have not "ended a move" entirely over lapping/touching an objective?

"Static" objectives

"Moveable" objectives

Many thanks
