On my server that are people who seem like they absolutely will not give up their epics.
Even at 70 I see people clinging onto their tier 2. Bloodfang, Nemesis, you name it and people are still wearing it.
They spent so long getting them that they don't want to let go, I guess. There's a warlock in my guild who made the HWL grind twice (!!!) who replaced next to nothing of his pvp gear by 70. He claims he didn't find better, but I'm skeptical. :p I'm the opposite - functionality is all that matters to me. If it's an upgrade, whether it's green, blue, or epic, I'm all for using it, even if it makes me look like something that just walked out of the rejects of an assembly line.
Same here. But I'm still holding on to 3/8 DS pieces for the set bonus. Not because I'm stubborn, but since I just haven't found any item combination (yet) that outweighs that ranged attack power bonus.
I honestly expected to have replaced everything at 70.. but uhm.. guess not :S
