addons DPS

what are the best addons for DPS?

If you are regarding to addons to show your DPS i think the best is Recount, it have a lot of show options like Damage Done, DPS, Healing done, etc and even graphical charts to show percentages of miss crit, etc

Recount on Curse

i hope its that you want

I would swear by this.

It's the same as the Damage Meter you got with the Cosmos complete, which I loved.

It's pretty small and un-obtrusive but can be enlarged so that all 40 members of a raid are visible, and is VERY flexible. It does DPS, Dmg Done, Healing Done, Healing Taken, Dmg Taken, Hits Taken Per Second, Dmg Taken Per Second, Overheal, Overheal %, Cures Done, Cures Per Sec and Idle time (to name a few...)
You can switch between 4 of the selected modes with a button found on the meter itself for quick use.

Basically, it's kick ass.
