keeping your stamina high ranks pretty high in survivability. as it governs your attack speed and mobility, you want to not let it fall below 80% ideally.
relying on divine fury works if you have very high mana regen, otherwise it means you'll be casting it over any other ability, and you'll always be low in mana, not to mention at a defensive disadvantage due to lowering your defensive chance.
a stamina leech weapon is probably the best option, as it does return a large ammount of stamina, it's only disadvantage is fighting high resist foes, you won't get any decent leeching, and will put you in your place unless you have a backup. mobs generally have a low resist, players generally don't.
stamina regen properties are a good backup to a stamina leech weapon, albeit slow. however, stacked beyond 12 is pretty noticable, and you will rarely need divine fury to refresh when complemented with a leeching weapon when fighting high resist foes.. there are more vital armor properties like resists and defense chance, and i'd prefer stamina increase over the regen. mana regen is a better choice too.
focus isn't a great option, as there are many more effective use of skill points, however, it will regen stamina and mana passively, and works well in conjunction with non-med armors. i wouldn't recommend it much, though i have a character on siege that uses it, and it is vastly underrated given limited equipment ratings.
