I beat Twintania like 20 or so times with my FC but I also joined some PF pugs who who said they were farm groups or whatever but none of these groups ever won in PF. From my own experience is pugs can't dodge twister at all. They do not know about focus target or have bad raid awareness when it comes to moving when she is casting twister. Which was the easiest part for my FC we had more issues with snakes and dive bombes but back in 2.0 when we were doing progression on this fight once we got past dive bombs it was an easy kill and almost nobody got hit by twisters.
