i used the following set-up 1 month back to guardian a paladin
dual spirit 35%
fcr ll ring
2 pala 20 fcr amu
might merc with insight
BH, vigor, BA, Conc maxed
remaining in sacrifice
the char tore through everything with ease
Yeah, that's a similar enough setup to what I did with my hammerdin for an Uber-killing setup and later for running around pretending to be a Zealot, so I'm sure it works. I didn't dump points into Sacrifice (mainly used Smite on bosses anyway) or use a Might merc, but the rest is pretty similar. I still keep the pseudo-Zealot gear (Guillaume's, Gores, crafted Blood gloves, Verdungo's, Highlord's, Raven Frost, crafted dual-leech ring) in my stash. Even with pure caster gear, switching to Grief/Exile easily clears Achmel's mob (on /players8). I hear some people use Holy Bolt for that, presumably because they don't have Grief or something.
Ye, I meant to say (and was thinking of) Faith and not Beast.
Well, you did use the number for Beast instead of Faith, although I'm sure Pride + Might merc + native Fanaticism is higher than Faith + native Concentration anyway. You'd have weaker Hammers and a stronger Zeal, basically (strong enough that Hammers would usually be redundant, I'd think, but then there are those magic immune monsters). I'm still sticking to my Prayer/Insight merc, though.
