before finished main story, i really dont know about CM, coz what im focusing is FATE and after that Class Quest for AF, then finish main stroy...

but when im queue DF for CM, i entered, all people is start running, and at the same time my pc choose that time to crash, luckily when im login again im still at CM, but all people (8-man dungeon if anyone not yet know) already i dont know where and enemies still there (coz speed run), and i run follow them and luckily not attract any enemies.

just before 1st bos, then again my pc decide to crash again(i dont know why my pc, since 1st day playing FFXIV arr, it choose this time to crash twice -.-"), and all people already fighting bos.

then im wondered, why when my pc crushed(so i dc), they really dont care about me, they don wait me? then after finished 1st bos they teleport  to i dont know where, so i just run outside and i pulling some monster,and the monster destroying the bazooka? then they start sound me, why dont follow everyone bla2, i really blured at tht time.

then fight last boss, they all go to bazooka and do something and left me again..and beat the bos...

this is the terribel DF exp i ever had..ever...

so after finished main story (luckily ultima weapon i have a pretty good party), i understand, many people looking for CM Speed run to get allagan tomestone.
so i have been paired with THAT people, speed run for allaan tomestone

i dont blame them really, but SE should do something about this, they should pair 1st timer to do dungeon, if u already completed the dungeon, then only u will be paired with people who completed the dungeon. coz this really make bad exp. at least for me.

im definitely going to speed run CM also for allagan tomestone, but i will explain for 1st timer, just a quick tips suffice.
