Ok, I have been buying Paizo Products for a very long time and I have to say this is the first product I have ever purchased that really blew my mind on how poorly done it was.
I mean it's just a re-structuring of the spell blocks for use as spell cards. If anyone has bought the D&D 5.0 Spell cards you know what I mean, but I just bought the PDF version of Primal since my wife is starting to play and is playing a Druid..
The PDF is structured in a horrid way, you can't print them out to the size you want, you can't print them in multi-cards (spells) per page and get this... every other PDF page is a generic "Primal" page... So the whole PDF is 174 pages and half of them are wasted space.
This whole product needs to be rethought out by Paizo... Secondly, why would you only do it for spells (Cantrips - 2nd level?)
Please re do this product.
