Ok, so there are diferent opinions on this, here is mine...

OMG, i can not stand it...at all. I was introduced to x-perl at lvl 60, now I can't live without it. After the latest patch, I stopped playing wow until x-perl got updated (or until I found it). Can not stand to play without it I'm afraid I find the default UI bland, not big enough, hard to interpret sometimes and not enough information included with it which I need/want when I'm healing. Thy are starting to get better but nup, not having any of it!

So yea, X-perl is THE addon I would choose if I was only allowed one.

How about you guys? Do you love/hate it? What addon can't you live without? Could you only live with just one addon? kgo...
