No, the 'slow' development of CORE is a result of the meticulous testing those guys do over there. I haven't been involved in it for a while now, but every time I check there's someone testing one function or another, and fine-tuning one element after another. As Hagar says, they're not a commercial group so they don't feel the need to get things out in a hurry, just the need to get things right.So some guys from CORE with you included are actually working with AoD devs to make a new product. This explains slow development on core mod!
You'll be amazed by how balanced and 'smooth' the mod is when it arrives.
