EDIT: as I was typing new version released, melee following distance reduced
I have just run Scarlet Monastery Cathedral, I have just run it, I tried to tank it every now and then, I would jut run to the nearest mob after the tank had finished a kill, got kicked from the group, tried reducing my pull distance to 1, made no difference. Other times I just sat back and watched the action

Can the melee class be made to be always within XX yds of the tank, sometimes I am sitting back with the castors trying to start my attack

Not sure if it Hb or IB though. Is it a bug, not sure really if it is worth reporting.
I won't attach a log, just noticed it records the loot getting rolled on, can't be that hard for Blizz to figure out what run it was

I do notice there are compile errors for the rogue in it though, maybe thats the problem.
