Here comes the infamous WoW "never ending" paragon rep.
Big fan of that. Maxing the rep and not getting any additional reward feels lackluster but luckily these rewards are nice enough to be a worthwhile boon but not so OP as to change your core gameplay loop to be focused only on the reputation itself.
That's actually nice.
a brilliant change, adds another source to obtain gear for a resource that is automatically looted (if you have a good boy)
They can in fact stack, so you don't have to collect them each time. I have had 3 or 4 sitting there for my character at one time.
