Revisiting the Wild's breath...

I have finally cleared MOST of the BotW DLC. Trial of the sword is raping Link's ass.
Here are my thoughts about it...
The Champion's Ballad is REALLY worth it as a DLC due to the extra story stuff revealed on it. Especially for Zelda, who needed a bit more exposition.
The gameplay ekements added are a couple of shrines, a small mini quest with a one-hit obliterator... fighting one of the dead shrine dudes, reliving the Calamity battles with crappier equipment... all for Link's divine beast Motorycle Unicorn... and shorter recharge times for Daruk's protection, Urbosa's fury, Regali's gale, and Mipha's grace.

All those chuchu jellies gathering dust in your inventory will become useful as fuel for your bike.

Trial of the Sword is a way to power up the Master Sword by doing sets of trials that are Eventide Island on steroids.

The last part of the DLC is literally different outfits from other games. Some are good, due to the added effects like the turd locator mask, others are a waste of space.

All in all, the DLC is a mixed bag, there are a few good things, buuut they're only available when you're "near the end of the game"... the rest is a bit blah.

The one thing we need is a "100 years ago DLC". With maybe a slightly limited version of the world to play a series of flashbacks on Zelda's quest to awaken her power.
Let's say that the Ancient Book of Mudora had its pages scattered across Hyrule. Impa gives Link a quest to find all the pages. If you find all the pieces from a region, then you can unlock a playable flashback at Impa's. Maybe the Yiga are also looking for the Book of Mudora as well in order to ensure Calamity Ganon's victory. But a guy could dream...
