Mods are a important part of playing the game, some mods make playing easier and more enjoyable.
Change your interface to suit your playstyle, and post it here.
Just remember, dont rely on Mods to make you a better player, they wont. They are there to give you information, thats it. It is what ya do with that information that makes you better. Example that you will understand all to well.
If your in a instance with 9 others and your sole concern is a fucking DAMAGE METER, your pretty much screwing the other 9 guildies your in there with. Your not focused on the fight, your actually not even fighting the boss, your fighting a meter. METERS DONT DROP LOOT. if your number 1 and ya dont kill anything, you cant blame the rest of the group for failing. You are part of the group. 2 people dont make a bad raid group, it takes 10. 2 can be replaced.
Same goes for all the mods. dont play the MOD, play the game.
