I think the part that most people have a problem with, is that these addons become mandatory whether you can perform well without them. Someone who isn't that great, but has all the addons and uses a cookie cutter spec, will be recruited over someone who is amazing but has an off beat spec and no addons. I was lucky enough in WoW to get to a point where no guilds cared if I had all the 'mandatory obligations' because I had a great reputation as a very good player. But finding a pug? I could only get into one of those if someone vouched for me. I'm not really for or against addons, I have used them. But I didn't use them all the time. I think the problem lies more with the player base wanting to use gearscore, and mandatory addons. But I guess if everyone played better in pugs, there wouldn't be a need to discriminate.
