Tip #24: Taking a Metered Approach
Should you make use of the Recount addon? Should you use the WWS combat log visualization website? What about WorldofLogs? The answer is yes, yes, and ... yes.
Recount is far more than "who is on top of the meters". You can drill into it and find out your shot distribution and further in for %miss, %crit. You can make sure your pet is doing the damage types it should. You can look at it for just a particular boss or overall. You can see what other people in your raid are doing and how they did or didn't do good damage. You can see it all as it is happening without waiting around. Please do not stare at it while raiding. You can have it minimized and look at it after a fight. Please do not share or spam the meters.
wowwebstats.com (AKA WWS) allows you to upload your normal raw combat.log. So does WorldofLogs.com. Both provide incredibly fascinating views and explorations of the data. In order to use it, you do need to have the combat.log file. You start writing to the combat log file by typing /combatlog. You also stop writing to the combat log file by typing /combatlog. If you have it on too long or don't delete the file after you're done with it, then you'll need to edit the file with a reasonable text editing program. Just make sure to have complete lines. If you always want to generate a combat log for a particular instance (or zone), you can use a great little addon called clsaver. It allows you to permanently toggle combat logging of an instance or zone.
Both websites show you aggregate information, but also let you slice and dice the information down to the boss, the player, and/or even the spell or spell effect. You can see who took how many ticks of standing in fire, how effective an auto-shot is, or even how many times your trinket proc'd. You can also see other hunters on other servers on the same bosses and look at what they did. I should also add that worldoflogs.com has great time-series graphs to see how a fight went over time. This lets you see how, when, and how often you spike your DPS.
