SS on a pally is horrible (unless you have to duel). Zaka > all shields on a pally.
However, SS is a marvellous solution for both PvM and PvP, if used on a lot of builds for other chars.
It's the best shield, imho, for:
- Javazon
- Wind druid
- Kicksins
and in PvP, it's used on nearly all chars. Cuz it has 35% dr, +str, good resists, a marvellous blocking percentage, a nice defense, and can be socketed with something useful (40 ed /15 ias jew or Um are common options). Oh, and it's indestructible = no gold to repair it.
