Was very dissapointed by this product. it is a very sloppy cut n' paste/search n' replace hack of the 3.5/Pathfinder SRD. The translation to 5e is really just above the minimum neccessary and lack any imaginative use of the 5e system.
This product need a total rework to be concidered worth the money. Just to mention the most (to me) glaring problem, the graininess. A Feat in 3.5 etc is usually one or sometimes two per level, in 5e it is one per fourth (about) and REPLACE a stat increase. It shouldn't be just a little fnutty plus in something, it should be a major flavour choice of the character! Not all Feats in 5e manage that, it is true, but this product fails it constantly...
Should have seen the signs, because they are written all over the wall, but my Feat-hunger got me into a buying frenzy.
Designers should really try to break out of the 3.5 mindset for the 5e, actually the freeform of the OSR is a better source of ideas currently.
