I think everyone is on the same page? We know we have people that fail mechanics, everyone is overly aware of who they are, and we want to have a bench to sub people out so we can continue to progress. A few thoughts
1.)We had a few things working against us this week, Buds hunter got locked out due to server transfer and mort was sorta unable to raid. Next week we will have 2 more people that we will be able to maneuver around to field the best team we can put together.
2.)Quitting only makes things worse, since that is another DPS spot that we will have to gear up/recruit. Pretty much adds to our identified problem
3.) 125 stat food hardly matters, unless you are a panda. I mean we just got a +10 ilvl buff for those who care to farm it, that puts us in a way better position than most guilds who cleared this content at 710-715ish ilvl.
4.) We are raiding Mythic only because we have cleared heroic, we have the numbers, and we still have a lot of people who seem interested in raiding and pushing new content
To be honest we don't have a whole lot of "mythic" raiders in our raid team, and a lot more think they are more elite than they really are. Talking to mythic raiders, they put a lot of time and effort into learning the intricacies of their class, researching strats, and evaluating their own play to figure out how to eek a little more performance out of their gear. We have some people who do some of this, but very few who can say they do all these things. Elite players change spec/talents to optimize to the encounter and their role (range/tank/healer/melee). Its not just all about memorize a rotation and stick to that, you need to make split second decisions every second based off what the encounter is providing. You need to know spells to use while moving, what abilities you can use to drop debuffs, or use as DR to avoid fatal damage.
