so you had plenty of time learning a boss.... doesnt mean its easierYou can't carry people on progression in 25 Progression. We aren't talking about farm. And we aren't talking about normals. We are talking the most difficult content. People who say"You can't carry people in ten man" are the ones that only do 10 man. Because if you're ever done larger raid sizes you would know about something. Being at range of other players when being too close of them spread damage. Things that kill one person in ten man take out multiple in 25. 25 man raids required more output per player than 10 man.
I've raided mostly 25's. Any time my guild was stuck on a boss the right before a reset, we'd drop down to ten man and get the kill. 10 man gave you boatloads of breathing room.
