Oh look, another one of these arguments about a 'high end raiding guild' that 'requires' you to do dailies. Newsflash; if you're in a high end raiding guild you've already cleared normal in the 1st week. Then you've cleared it on LFR. And you've done all of this w/o rep gear. I think you're just making lame argments because you either fail at your class and need the gear crutch or your guild really isn't that good and needs the gear crutch.
Whether you got gear in LFR or Normal or not, the point is that if you walked into the raid with quest/5man blues and killed the boss then that proves you did not need nor are required to have rep gear. If you hate doing dailys then you can farm normals and LFRs every week to get gear. Problem solved. Rep gear is an optional way to progress your character w/o having to do raids. It's a very simple concept to grasp.
