World of Warcraft PvP Guides - WoW X-Perl Guides
There are many UI mods out there, and many of them play around extensively with your UI. Many people have a favorite and will extol on its virtues for ever. The one that hooked many players, myself included, is the X-Perl Unit Frame mod. It is pretty much a complete replacement for the standard Blizzard designed UI as the only thing stock it really leaves on the screen is the button bars and the map. Anything to do with characters or targets is replaced.
X-Perl also allows you to setup additional frames such as focus, pets, and target of target. As a tank or as a healer I find target of target extremely useful. As a tank you can use it to see when the target has switched or is using an ability on anther character. As a healer I use it on some fights to spam heal the bosses target when there are many tank changes. Doing this makes sure you are always on the right tank without ever really worrying about who it actually is, if you see the frame change you just click it and keep casting.
Configuration of X-Perl is something that takes time. Do not expect to be able to install it and be up and running full speed in a few minutes, even if you have used it before. There are so many different configuration settings possible and so many things to move around that it just isn’t done quickly. Also sometimes the commands you are looking for just are not where you expect to find them, or at least not where I expect to find them.
