I agree with Z on most everything he said, what it seems like to me is the OP is angry that someone used logic to try and make them think instead of out right agreeing and is now acting as if they are a victim of some horrific attack.
Players like that really disgust me, I'm sorry if that sounds hurtful but it is the truth. They normally fall in the category of wanting everything there way and any logic provided to go against their blatant demands are met with the song and dance of "You attacked me you troll!"
The facts are simple to understand: Gear comes from many different places, it is YOUR choice as a player to put in the effort to get this gear. It is the very same rules "raiders" have tried to enforce on the casual player by telling them if they want the best gear they must step into a raid (Even if they hate it) to earn that gear.
Well, now you must endure dailies, and other forms of "Challenges" no matter how dull or boring you may find them for your upgrades. If you do not like it, simply do not do it. Gimp your raid? I highly doubt that, unless you are trying for world first it's not make or break the run.
Its a very common thing, not only in WoW or even in gaming, but in life. So many people seem, to be frank and blunt, so entitled that they literally and truthfully adopt an attitude of "agree with me or you're trashing me". 90% of our society today spends its time trying not to offend kids and even adults that when they are faced with some form of pushback, even if it be intelligent and logical, is met with cries of harassment and such. But I guess I'm getting off topic.
The point is, there are tons of avenues in this game for getting gear. They are not all "required" by any stretch. If LFR didn't exist, then the "super-elite" would still be doing EVERYTHING to get their gear as high as possible. That's what makes them so. To everyone else, yes, there is the temptation to run LFR every week without fail because of the fact that it does provide a chance at getting gear, and we all want more gear to become stronger.
But at the end of the day it is the responsibility of each individual player to evaluate the potential gains of doing an action like LFR (more gear) against the potential cons. The fact is, it is possible to raid without significant LFR gear. So every time you step into LFR in order to acquire gear, you are making a conscious choice to do so, and could just as easily choose not to. And while choosing to not run may not be 100% optimal in terms of character progression, I don't believe that you are so significantly hampered as to be worthy of negatively affecting a much larger section of the community.
