Addons that you cannot play without.

[reflectional]

So I haven't seen a thread like this if i am wrong I am sorry but in the case that I am not.

Which addons can you not play unless you have them installed.

For me its:
Tidy Plates (helps me know who do and don't have aggro on when tanking)
Razer Naga Bar-mod (like domminos (I hate the blizzard button setup)
Postal (clicking each mail is boring lol)
