I have a rogue that I spent months gearing and stuff, too - I love my rogue, he's fun, and nostalgic. I don't play him at all because it's detrimental to the bracket's activity and quality.
The argument I'm making is that not everyone shares our opinion, and will continue to play their rogues. I think they're justified, and it's solely a matter of others' opinions that you're presenting.
Remember that short amount of time that hunters were the big thing (still are, but less so), and EVERYONE was complaining about how hunters ruin games, how hunters cause GY farms, how they were unfair, etc. etc.?
And you kept playing your hunter..? Then druids were FOTM, so you made a druid..?
I'm not going for low blows here, I'm just saying that you know exactly how it feels to be proud of a character, love playing it because it's easy and BiS, has a respected name, and is FOTM. I did too for most of wrath and cata, don't get me wrong.
