Yeah, I totally agree. I think it's pretty crappy that people want me to carry the alts they are too lazy to gear up on their own just because their guild carried them to 7/14H. Oh, wait, that's not what you were saying? Oh, I see. Do you really, actually want every PUG leader to create a sliding scale of item levels indexed by your "main's" heroic progression? Would you do that? I bet you wouldn't.
LFM Fresh Flex 2 - need 2 heals and 7 DPS - 510+ if you're 14/14H, 515+ if you're 12/14H, 520+ if you're 10/14H, 525+ if you're 9/14H, 530+ if you're 8/14H, 535+ if you're 7/14H ... Oh, looks like you didn't make the cut, anyway.
Your 7/14H means nothing. My raid carried a recruit to 7/14H on his trial week and then I watched him turn around and advertise himself as 7/14H in recruitment posts as if he'd done the work to get there. We have subs who do maybe 70% of the output they should who are 10/14H because they were the only available option when someone else was absent. We just had our worst DPS poached by a guild who's switching to 25. He doesn't even play his main well and he was pissed off that we wouldn't carry his 522 priest (who did less DPS than my disc priest in shadow spec and less healing than the tanks in disc spec) on cleanup nights. Your post sounds exactly like him.
Meanwhile, I have an alt who got to 550 average item level with zero flex or normal SoO kills and three LFR wings completed (wing 1 twice and wing 2 once - two pieces of LFR gear), another alt that's 571 from running in a 25-man GDKP, a brand new 90 that was 536 after two weeks and another that's barely seen SoO sitting at 564 (maybe 30 kills of all bosses combined on normal and heroic). You're lazy and your alt is probably bad because of it.

Your cherry-picked example doesn't demonstrate that. Honor gear is not 99.9% the same as valor gear. Even one crummy PvP power socket bonus is more than 0.1%.
Your hyperbole aside, I didn't say honor gear was bad. I said it's not identical to PvE gear in usefulness for PvE and that's not debatable, it's a simple fact.
