Addons that help

Here is a list on links to addons that help all classes

OmniCC

 OmniCC is an addon that adds text to items, spell and abilities that are on cooldown to indicate when they will be ready to use. In other words: it turns all the standard analogue cooldowns into digital ones.

GTFO

 GTFO provides an audible alert when you're standing in something you're not supposed to be standing in. In some cases, you'll be warned before you start taking damage. This mod improves your situational awareness and is recommended for dungeon divers and raiders of all skill levels as even the most seasoned veteran sometimes needs a reminder to GTFO.
