make the next campaign an "elite" one.
by this i mean :
-the only players capable to play it should be atleast level 40.
-make each mobster a true pain, not like mummies, kinda like how the crocs where b4 the update, including the debuff , that way, the mynas gen, as we call it, wont continue over and over
-the bosses would be then impossible to solo or even duo, and ud need a well organized team just to get rid of half of their hp. this will increase teamwork and put some rea challenge into the game, for us lvl 45.
-as it has been proposed before, quests should have some exclusive items (redbone)

post any ideas to make the game even more challenging!
and tyyyyy devs if u consider this
