Depends on what else they get. If they stay T3, no armor troops with 1A no point reduction in the world will make them good. Also as they are Fast Attack forever now they do not get objective secured either. Wasn't a fan before... probably won't be a fan if it is only the reduction in points.
Space Marine Assault squads are not the best troops around either but bring T4, HoW and 3+ save to the table. Dont expect Hellions to compete with that. And if they can't compete with a sub par unit...
