This is what I'm striving for...... can't get enough for Mythic thou, good players tend to get butthurt if you have to bench them, and you can't roll with just 20 cause people miss for various reasons when you are trying to rely on 20 to show up for raid nights all the time just doesn't happen.
My new idea is try to find other people in other Heroic only guilds with players that want to do mythic on an off night to be my "Bench" not sure how that's going to work but by god I'll try.
