One more question reguarding the hunter damage calculator. What would be the best fight to enter in (time, level of boss, etc.) to get the most accurate damage per second. I have been told that Patchwork is the best boss to test you damage per second on. Is this true, and if so, can that boss fight be entered in the damage calculator accurately? Once again, truly great work, also one thing I would like to see in the future is possibly a drop down list for 10 and 25 man raid bosses. Thanks again, guys.
It makes no difference what boss you are attacking. They are all level 83, and all WotLK bosses have the same armor value, unless there are bosses like Teron or RoS back in BT who had lower armor than the rest, but so far I haven't seen anyone mentioning something like this. The only variable is the movement required, that's why Patch is considered the best.
About the fight length, leave it at the default 6 mins. You don't use the spreadsheet to simulate a specific fight. It uses ideal conditions that you can never replicate in a live raid. Just use it to pick the best gear/rotation/talent options.
