Elva, Raglin & Shu-Zen are totally worth booking just on their own merits.

As for the rest, it really depends on where else you might use them.  All of them offer value for Hard FW progression when you get there.  

I wouldn't book dupes just for Forest, but a second Thor would certainly help you in Hydra. 

Morrigaine is all about her passive, she doesn't need books.

Mortu has a block heal on his a1, but even booked it's not 100%. For him I;d say it depends on what other block heal champs you have. But the simple fact you have morrigaine (i regret skipping her fusion) means it's probably not worth booking mortu to be a heal blocker. Kytis, Rowan, and Veno are all epics who are better choices for it than mortu anyway.

Whatever you decide, and I agree with wiley and rat, book them during training tournament NOT events (no points)

I am sure Trips meant to say "Book Over PR CVC"  😂

That's my new definition of early game, still saving/using resources for cvc.

yeah, I've reached the point where if i need to grind cvc points i just gem energy potions and run hard spider 10 or shogun 25

Booking and pulling fragment champs get saved for fusion tournaments

Early Game Forever.  

To each his/her own.  

Points for Books in a Champ Training Tourney are pitiful. 

I am gonna do 400K+ every PR CVC no matter what, so I'd rather take my 3k/Lego Book there than the paltry 200 you get for a Training Tourney.

I plan to build a 2nd Thor with 6 pc merciless for hydra.  

Yeah, I'd probably build a dupe Thor just for hydra if i pulled one.

I'm still a "newb" acct, too.  400k for a chance at a sacred?  I'm in. 😁

I do 450 to 500 without books or other non cvc only resources 

Tag, forge, gear ascension, fw, ...

Says the guy who also says his clan doesn't care about CVC.

Doing 500K doesn't sound like not caring about racking up CVC points to me. 

We have a 0 min req, its completely random who participates.  I literally only forge and ascend gear during cvc so it is no wasted resources and we only win slightly more than half of pr probably. 

Samsies.  We dont even trt to win PRs anymore and im still always over 400k cuz im a dummy. 

We've been on a good streak lately of good matchups.  If its close we usually win, we have a strange mix of spenders and casuals and weirdos like me

We are the best t6 siege sandbaggers around though

You are a nation of one.  

I am stealing my own thread.  Mavara, Ezio, Fabian.  Do they deserve books?  Not for Grim.  

I will speak on behalf of Ezio.  He's a pretty good champ, good kit.  But he could use the books for him to be more effective.  Mavara is just nutty good.  I'd say 100% yes on her.  I know next to nothing about Fabian.

I went from no legos worth booking to too many.  

I see all 3 of them used in arena a lot.
