Was just directed here by Cheeky, this is truly a wonderful resource.
I just wanted to throw my spreadsheet out here as well. I use it strictly for gear comparison, not absolute numbers crunching, which means I can make the convenient assumption that most factors cancel, and I can just model a basic shot rotation.
I have already been made aware of its deficiencies, forgive me for coming at this late in the game where so many have trod before, I am only just now learning some of the work that has been done on actual cast times and such.
