Elder Scrolls wouldn't be the same without the o so familiar dungeons.
(And perhaps Cyrodiil will have dungeons were you'll be able to pvp?)
I am of the opinion that pve shouldn't be the only area where you'll encounter recognizable scenario's of the TES games
So if there would be dynamic instanced pvp dungeons would you prefer them to be 1Vs1 or group vs group?
The first thing you'll probably do is choose a setting for the pvp battle;:cave,mine,Dwarven Ruins,Fort,Tomb,tower,sewers
Each of these areas have different "tools" to use against the other player in a strategical manner
Perhaps before the battle starts each player/group gets a minute or few to set traps in their zone and perhaps a secret hideout?
Other minor traps you'll be able to place during the whole fight
Don't know yet which ones you'll only be able to place before the fight starts,perhaps the ones that instant kill..
the ram ,traps to pierce the enemy or chop off their head,..
each dungeon has different tactics and you'll be able to do different things too(feel free to suggest on this)
on towers you could push your enemy from a cliff
in mines you could bury your enemy by letting a tunnel collaps
When in tomb setting you could push the enemy into an empty sarcophage and lock it ,then only their allies could free them with a channel skill
In dwarven ruins you can activate cool stuff
Perhaps i'll go more in dept here if I have more time but feel free to tell what you would like to see here
