Since I seem to be supremely poor at PvP, I thought I'd wander around Cyrodill first and try for the Cave Delver achievement.
The delves in Cryodill seem to be set up rather differently that in the rest of Tamriel in that they seem to require you to dispatch 3 bosses per delve. The problem I'm having is that in some delves only 1 boss seems be resident, once that's dispatched another will respawn 10 or so minutes later. I managed to clear one delve after a considerable amount of time (and several gaming sessions) but I'm currently having massive problems in another.
The delve itself (which is miles away from my respawn points) is just a small 2 cave system with 3 bosses to kill, only one of which appears at once. When the boss is killed you have to wait around 10 minutes for a re-spawn, which seems to be random. Currently I've spent what I would estimate to be about 4-5 hours killing the same two bosses over and over again, waiting for the 3rd to spawn; it never has.
Since everything else in the system respawns in seconds I've done a lot of fighting and brought my armour down close to zero twice before having to give up and go back for repairs; I've still haven't completed the particular delve.
