Progression/Ilvl/Skill

Our raid team has been working on Garrosh and some people of the team have convinced themselves that their gear is not up to par and there is only one way to kill him. Everyone has an ilvl of 560+, so there shouldn't be any reason why we can't and this frustrates me. Our team in the past had an open mind on trying encounters slightly different then the most common method and it worked for us. Now a days, people are so closed minded on how to do things and that there is only one and nothing different can be successful. The collapse of our team is imminent, just who will be the first to burst? When it comes to ilvl/gear and it being the only reason in people's minds why we can't kill a certain boss, I say it helps for a faster kill but skill is equally important to success. Skill will help you move and be aware of whats going on and gear helps you perform those tasks....both equally important. So if you suck, you suck....if you have gear and die, get better and don't die....if you have a willingness to learn and try new things, you have potential.
