Durability is manageable when it comes to weapons that has splinter weapon mod.
Splintering Weapon is an item property found on certain weapons. A successful hit with such a weapon causes a glass shard to break off from the weapon, striking the victim to cause a bleed effect and forced walking.
This property stacks with the bleed special move to cause additional damage and extend the duration of the special attack.
What does this mean? you can use a POS splinter weapon to get proc then just switch to imbued bleed weapon with good mods (psss.... 2 dexxie rotating bleed and splinter proc = a permanent pvp char in turtle speed

)
Its all about team work, just because you are slowed does not mean you will die if you got teammates to back you up.
