After seeing first hand that Bethesda can make some significant and challenging enemies throughout their recent DLCs, I would love to see them bring back a coliseum type DLC that implements not only epic enemies and combatants, but also with several faction tie-ins. Something on the scale of the coliseum and the trial of nine bloods from oblivion meets the spirit and fun of a Medieval Style tournament.
I Would love to see a battle royal for example champions of various factions duking it out for top spot, or perhaps some quest tie ins into the actual combatants/factions involved. Anyways just some thoughts, anyone else would like to challenging fights and epic encounters?
