I've already got the s2 shield, and passed on the nb shield since it's not impressive compared to the s2 imo. What do you think of the s2 shield vs the legacy defender? I'm still liking the s2 shield better but maybe thats because it took so much effort to get it.
You lose 2 block and 22 defense from the [item]Shield of Impenetrable Darkness[/item]. You gain nearly 900 armor and 15 stamina. There's no way the defense loss makes you uncrittable (gogo resilience!), so just take the [item]Merciless Gladiator's Shield Wall[/item].
And it's also far better than the Aldori shield. Again, large armor gains, plus a large block gain. You end up losing some stamina (3 points), but the armor makes up for that.
Aldori is probably good to have though, because it's very good for aggro tanking.
