who agrees with the new tes having 2-3 players free-roam co-op and not being a mmo

Nah, I like my Elder Scrolls single-player only.
Spending time developing a co-op system is a waste of resources that could be used to improve the maingame.
And we already have a thread about that http://www.gamesas.com/index.php?/topic/1119156-official-tes-multiplayer-thread/

I wouldn't mind a mode that allowed you to pit your character against a friend (with many variables such as help) in the arena.

No. It would only take the game longer to complete. Taking away resources which could otherwise be spent on building an amazing single player experience.
I think it's best just you on your own in the game world anyway though, people would just want to run around as fast as possible hitting everything in sight.

Might be good, not for me.

First of all, there's a thread for this, linked above.

Now, you have to remember that TES games all revolve around you, the player. When you're changing your gear, the game pauses. When you go to save your game, the game pauses. When you talk to NPCs, the game pauses. TES games are just not built with multiplayer in mind, and IMO it would take away from the experience.

This would be better in the multiplayer thread, or suggestions for TES5 threads.

People tend to have strong feelings about it, and its better to keep everything in one or two threads.

Yes, we do.
