There's nothing wrong with Cackle.
It's a buff that doesn't even do anything unless you buy other hexes that work with it. And all those hexes are gone the moment people step outside a very small zone.
It's not a free action. It's a move. You can't even keep up with most of the group if they move their full 30 unless you do nothing BUT cackle.
This means you can either cackle and buff or move and cast and let the hex dissappear.
Nothing wrong with it.
