Rite of the Nine “free to play” event

I haven’t seen anything addressing this but when bungie call the LTE free to play do we think it is all free to play?

Currently Prophecy is FTP but spire and GotD are in dungeon packs.

Free to play to me would mean I can play all three without buying LF or WQ packs but I’m not sure if it means the same to the rest of us.

As someone that doesn’t have all the packs it would be nice to know what I’m getting.

Do you think the WQ pack is worth it? The bow seems not great and the sword looks like more of a meme than something worth £8
