I hope Alex's input in the co-written songs is significant. Please remember that he not only composed FEAR all by himself, but also pretty much wrote the whole Dangers of the Faithless. I'd hoped his involvement in the writing process would rather increase than be smaller. We'll find out soon, I guess. As for Greg, yeah, he never wrote all that much, but did contribute here and there. On the last record he was the major composer of Leave Me Forever. It's always good to hear his input.
I totally hear you about Gene. I was also certain he wouldn't stay, but at the same time kinda wished the opposite. Well, we can't get used to anyone behind the kit in Testament. The same will probably apply to Mark or anyone who's next. It may be painful, but also enriching.
