Return of Reckoning

So yeah, any addons that most suggest one always gets?

I use several: SoR, Enemy, Pure i like em the most for UI there are ofc many more but those i always run.

Enemy: Your bread and butter addon for marking players (both enemy and friendly) permanently with a flag
SoR: for keeping up with zone development. you see how far zones are progressed and AAO
GuardPack:to track guards (this includes Teather to see who you are guarding and who is guarding you with a nice visual line between you and your guard)
Buffhead: to track immunities on you and enemies with visual icons above heads
aggro meter: if you need to do pve and want to track who has and will get aggro when

Since State of the Realm (SoR) has now been mentioned twice already, just a quick heads-up: this addon has been built into the client a while back, so it is no longer necessary to add it manually.

GuardPack on all your characters.

DPS needs Buffhead, properly setup and you can quickly see if a target is Guarded (and by whom), how many HoTs you can, if the enemy has a big spell like "parry everything for 7 seconds".

Healers needs Enemy, again properly setup, so you can see big debuffs that works as tells for who in you party/warband is about to get hit by the enemy before the damage starts rolling in.

Tanks need both. You need to know who is guarding your DPS's target with Buffhead, so you can punt that tank away, and you need the tells from Enemy to help you know when to swap guard.

WarbandLeaderHelper if you wanna lead pugbands thru chat.

Shinies for a good AH, vanilla one sucks.
