I think everyone who played TESO IV would agree that the Arena where you would play as a gladiator fighting NPCs to the death was a great and very fun feature.
I spent hours training my character to overcome the challenges on various difficulty settings. I think something like that would be great in ESO.
And yes before people go off, I know there are quest lines in the game where you would go into an arena setting. I talking about a feature, more of a solo event, a trial per se with a scoring and ranking system.
I don't want to refer to Warcraft here but I will for the point I'm trying to make, Blizzard gave Warcraft a feature called "Proving Grounds" which is a kind of Tank/Healing/DPS trials event. I immediately thought of TESO IV gladiator Arena when I first read it, and the first thought I had was genius! I think it would follow the lore very well. I'm not suggesting Zenimax copy what Blizzard did in Warcraft, but more of what Bethesda did in Oblivion.
