As long as the rogue was making pugs reserving bindings for himself he had every right to get them.
Also TF is BiS OH for a rogue even compared to iblis...(hungering is another story)
remember that offhand swords do White damage and need to be faster than everything else, thus weapon speed is mandatory for a rogue's offhand (see Hakari OH example).
Don't be confused from the noobs saying that swords such CTS fit as offhands...cause they judge only from the dps and ignore weapon's speed, which shows they don't really know their class.
Yes ofc its BiS tanking for a tank no doubts but still a great OH for rogues.
