Your point seems to be "if I discount some of the material WotC has released, they have not released enough material." I don't understand this argument at all. There are folks who are playing through both MINES and HOARD. The next book will be out before folks are finished with HOARD. This output is as quick as D&D has ever released new material for a new edition.but the amount of official product for 5e is way too limited for my tastes-this 2 months after phb was released. take away hoard and you have a phb and mm. take away phb and you have hoard and mm...well you get my point. so at present...and following the logical assumption that if i bought phb i wouldn't then turn around and pay 20 bucks for lost mines...i just have hoard.
You're of course welcome to not like what WotC is producing (or to be turned off by tepid reviews), but this idea that they have somehow dropped the ball in not producing ENOUGH adventures is demonstrably factually inaccurate.
