I gotta say, when you have a team that out of the 8, MAYBE half of it tops is 50, and the rest could be anywhere down to the teens, and you decide running 4/8 is a good idea....really? Sometimes it can work, but that can be because the 50s and anyone close to that is pretty tough but, otherwise, it's not gonna help the others, their acc will be in the dirt, damage likewise, so on and so forth. Speaking for myself, when I run a 50 team, I ask at least for people be 40+. I start it off at 2/8, and if it goes well, go from there. Otherwise, you have teams who keep wiping on near every other mob.
