I want to ask at the GM what is the logic for delete the trinket bone link by npc for classe like rogue, while those who had taken it in the past it has not .
my question is...why??? why this?? what is the sense?

And an another proposal, why not merging the Cata server??

I'm fairly certain that the logic behind it is two-fold; the item was never intended for Rogues, and that it unbalances pvp.

why they have left the other thieves who took it before the trinket ?

Because taking away something someone invested their time and/or currency to get isn't something we'd like to do.
Additionally, we expect the Rogues with the item to fade away, or come to the realization that it's not an item a top-tier Rogue would want to use.
