I join your conversation about FFG policy with the CK, and while I fully understand those who already own the 1st Edition of Descent (which I don't, I remember seeing it at a local game store back to 2004) and feel a bit "pissed" by what is actually going on, I who don't own that first Edition, I of course don't feel stolen by their H&M Packs (oh wait, every time you guys use those initials, I think about that swedish clothes Markets : H&M). My question would rather be : are there so few differences between the old heroes/monsters sheets and the new ones ?
Well minis are different and the abilities (heroic feats) of heros and monsters got changed. Some of the heros and monster were too strong or weak and got reworked.
