The new ticket idea honestly says quite a lot, they are really trying hard to push us back to LS run content as it used to be and away from pug stuff. The ticket system favours a LS run system where you do the NMs set aside for peoples wants and not the ones you capped on gear from.
That's the only reason I can see for such a system when it would of been easier to do something far better, ie. trade any of an certain NMs drops to an NPC to build up points for the rarer of the items that nm drops.
