"amateur-ish to bash on the Maya"?
Hardly! I've been using Maya since 1.0 (actually PA 8),
rartist, calm down and read the entire sentence that I wrote, again:
"It personally strikes me as amateur-ish to bash on the Maya renderer without mentionning specific reasons. "
I'm glad you gave explicit reasons: in your experience, Maya is crash-prone, you wish it had Radiosity, and there are some confirmed bugs that you're waiting to get fixed. Message understood. 
Now... thank you for sticking with AW and pushing us for improvement. The fact that your still using our product must mean that there are some things that Maya does right.
