I don't take credit for writing any of these mods, this is just a mod compilation. This is a very memory efficient modpack. When making this mod pack I tried LOTS of different mods until I found the ones that used the least amount of memory. I'm going to stay away from any class specific addons to make this friendly for all classes. I plan on regularly updating this pack. I don't plan on changing the user interface, because I like the standard one and it is confusing to most people. If there is a mod you don't like, click addons on the character select screen and disable it.
I recommend you do a clean install of this modpack.
Automaton - Automates redundant tasks, shift click on NPC to disable
BigWigs - Boss alert mod for 10 & 25 man raids
DragEmAll - Makes all frames movable
EasyMail - Upgraded Mailbox
GatherMate2 - Displays location of all Herbs, Mining, etc
GearScore - Gear overview
Lightheaded - All the quest info on wowheads website
LittleWigs - Boss alert mod for 5 man outland instances, must have bigwigs to function
Mapster - Map, instance map
Omen - Threat meter
Onebag - Turns all your bags into one big bag
Onebank - Turns all your bank bags into one big bag
RatingBuster - Shows meaningful stats for items (+25 agi = 1 crit strike rating)
Recount - A damage meter
Routes - Takes Gathermate data & plots an efficient route
Navigate to the World of Warcraft\Interface\Addons Directory and delete everything there (except for any of your other mods you want to keep) . Now that you have cleaned that up extract my modpack there. When copying files over, if it asks you to overwrite CLICK YES!! There are no permanent changes made, so nothing will get messed up.
You must enable "Out of Date Addons" at the character select screen.
Below is a video that shows you how to configure Gathermate / Routes. Skip the first part that shows you how to download them, you have already done that if you have my modpack.
