I think it comes down to the way the comic industry works. There just needs to be a new name on the title to give it a new chance at life. In the old days, writers could resurrect their series with a good run or change of direction. Now, most don't get that chance and the smart ones don't stay on for more a year. The average comic reader seems to jump around like hotcakes between the new cheese and whatnot. So having the same writer would've been a poor move as retailers would not have had much confidence. It's sad but its the way the comic industry seems to work these days. It's also one of the reasons why I care less and less about comics.
That's defintiely true. I don't think IDW helped themselves at all in that regard. They were asking for trouble. The comic reading public (in the broader sense, not just TF fans) is very fickle and unaccomodating of change unless its "big", "bad" and by a star creative team
