Depends on the type of pally you play..if you have a hammerdin, that would go great wth it (all though you are losing alot of mana for the 20% faster cast speed, not to mention the damage reduction), I would be tempted to try it out and see if I did better with that or the Shako..all though I think the shako would be better all around.
If you are using a zealot/avenger type, then I would stick with the Shako.
i was comparing with shako, although i don't have extra 2 ber to test it, 2% dr would be doable if one would be willing to sacrifce hitpoint and mana for the fastcast and fast run. with 2 sockets, if extra dr wasn't needed, not sure how the replacement of charms might over tip the choice
thx for the comments, i guess i will mule it and hold on to it just in case
