There are two distinct schools of thought when it comes to twinking.
First, you have people who enjoy the aspect of gearing a character and the online pissing contest of who can be truly BIS. But that's just one aspect--those people primarily play the brackets because they like facing other twinks and enjoy rivalries and good, competitive PvP without having to run on the obnoxious, end-game gear treadmill.
Second, you have people who go all-out (even against pubs) and pop all consumables and everything they can in any game, because, frankly, they like to see big numbers on the scoreboard at the end of the game. As in: "Dude, I went 23-0 and had 3x the next highest guy's damage." Many of these people also routinely AFK when they see twinks on the other team.
For example, I know one warrior who routinely boasts about doing double the damage of all other fury warriors in the bracket, but when my premade faced his a week or so ago, we beat them 3-0 in TP because he was just farming kills mid with a pocket healer.
Conversely, I know another warrior who, if he's not facing a premade, puts away his Sul'Thraze and Destiny and uses the BoA swords, because he'd like to have a bit of a challenge. And he knows there's none to be had in going BIS vs. a leveler.
I consider myself, and most of the players I respect and would want to wargame with (or against) to be in group A. For me, at least, this is because my main involvement in the XPOff scene came when the brackets were separated and we could queue only against other players with XP off. We strove for fairness and evenly-matched games as much as possible. Most players had characters on both factions, and if one side won WSG 3-0, we'd switch the teams up a bit to ensure a competitive game. It was awesome. So in the current landscape, I'll usually hop on my ally to see if ally PMs are queueing, then switch to horde and put a team together so we can hopefully queue into the other PM and have a competitive game, or vice-versa.
I don't have a ton of respect for many of the people in group B. I think it's ludicrous to flask and pot and use sharpening stones, etc., against an enemy team with a bunch of levelers. It's kind of like pitting NFL players against Pop Warner kids--where's the fun in that for either side? I also think it's ludicrous to rely on an item that, when used in concert with other people also using the item, can mop an entire enemy team with very little (if any) chance of realistic counterplay. It's one thing to want to have BIS gear; it's another to rely on an item that all can agree is broken. In my view, Ram's is a crutch and nothing more.
Now, I don't pay your subscription, and I'm not trying to tell you how to play the game. What I can tell you is that I used to use Ram's when the ilvl changes were first instituted, and I realized it just wasn't any fun for me--either to play with or against. So I don't--and won't--use it anymore, and I have a lesser degree of respect for those who do.
