Me and Yar actually had a caster DPS calculator established and fully operational, however, we decided to make it more fancy by coding in some automatic spell sequences for optimal DPS. We came quite far but never finished it, so atm it is kinda useless. I'll see if I can dig up an old version when I get home from England.

I have it ready, but unfortunally I don't have access to my stationary computer (which has the file), so I am unable to upload it. Won't be able till the 12'th of december at the earliest, probably a bit later.
Though, that version is without the proper attackspeed for supreme cleaving mid chains for barbarians, since no one has really posted any in depth numbers of that attackspeed.
