The one problem I have with alts is not so much learning their different abilities, but making sure that I feel as comfortable playing the game with one as I do with my main. You can never have the same abilities with different classes, but some similarities may help you feel better with an alt.
Map keys and mouse buttons to similar abilities – I mainly play with a Logitech MX810 mouse and a Logitech G13 keypad. Their buttons and keys are all set to specific keys in the game, so that when I want to map them for alts, I just have to put similar abilities in the specific spot on the hot bar. For example, on my mage, my Mouse 4 and 5 buttons are mapped to bar buttons 2 and 8. For my mage, bar button 2 is Arcane Blast and bar button 8 is Arcane Barrage. On my druid, those buttons are Wrath and Moonfire respectively. However, on my rogue, they’re set to Sinister Strike and Eviscerate. On the G13, key G3 is Counterspell for my mage, and Kick for my rogue. They both interrupt the target, so it’s easier to know that the same key enacts a similar talent across different accounts. Similarly, I have Dalaran Brilliance on my mage in the same spot I have Mark of the Wild on my druid. Professions are all in the same places as well.
Load profiles from different addons – One of my favorite addons in Dominos. It’s an addon that allows you to arrange your bars in the game so that you’re comfortable with their position and size. What it allows you to do is save a profile for one character such as your main, and use that same profile for your other alts. That way, all your bars are in the same place across all your characters. Many other addons have global settings such as Titan Panel, but others may need coaxing to get them just right.
Set up the same window tabs – This is something I haven’t been able to figure out how to do automatically, but I have an extra tab in the game for whispers, and a whole window just for guild chat which doubles for World and Local Defense. This way, I won’t miss whispers and world event messages on any of my characters.
There are some settings you can’t copy over such as pets or mounts that one character has that the other doesn’t. You can fill them in with what suits one character better than the other (eg: Nightsaber mounts for Night Elves vs. a horse for a Human).
You may find that keeping your character’s UIs and keyboard and mouse settings more similar than unique may help with how comfortable you are playing an alt.
Has this happened to you? You’re in an instance or hanging around Stormwind and you hear this revolting noise which sounds like a cross between a bear sniffling snots and someone chewing with their mouth open? That’s the idle sound of a Worgen. Since Cataclysm has come out I’ve hated that noise. Now you can get rid of it.
There’s a mod on Curse gaming called Sniff-B-Gone. It’s not a true addon since it doesn’t modify your Interface folder. You have to do the work manually. I still need to do some research on this, but apparently Blizzard is allowing users to change the sounds in the game by putting their own in the <WoW>\Data\Sound subfolder. There was a post about it on the old forums which I can’t find now. I’ll link it if I can find it. There’s a hierarchy to these sounds which I don’t have in front of me right now, but the contents of the Sniff-B-Gone mod will remove the Worgen sounds for you by placing empty custom .wav files where the Worgen male and female sounds go.
A warning about this .zip file: DO NOT replace your Data folder with top-level Data folder in the .zip file. For some reason the .zip file’s top folder is “Data”. If you overwrite your Data folder, you WILL lose important files. You want to use the Sounds folder that’s one level lower.
Uncompress the .zip outside your WoW install and double-click the Data folder that was from the decompressed Sniff-B-Gone .zip file. Inside there you’ll find a Sounds folder. Copy THAT Sounds folder to your Data folder under your WoW install.
So, if your install is in C:\Program Files\World Of Warcraft, you’ll put the Sounds folder from the .zip file inside C:\Program Files\World Of Warcraft\Data.
Mac users can put the Sounds folder inside your <WoW Install>/Data folder.
If you already have a Sound folder, just follow the hierarchy from the .zip file.
