For Cata I've mainly been playing on my hunter, which require really no mods for the GUI. I use to heal as a paladin back in WotLK and for that it required suchs mods as grid, decurse, clique, etc. My main question is if mods are required now for raiding. My holy priest is 83 atm and I just wanted to know which mods I should grab before I start raiding.
It's been a while, I'm not even sure if the default WoW GUI has icons on which members have debuffs on, diseases, etc. Is the default WoW GUI enough or should I get something like Grid again? How many folks raid with the default GUI vs getting Mods?
