"Ber" Arreats is a rather foolish move. It will only grant you 8% PDR and that means you have 16% with Enigma, pretty much making it useless.
Grief+Beast does the most damage.
Nice going, you just lost ~45 triple resistances!
BB is actually pretty useless. The only few occasions where it could be useful would be versus Smiters, Zealots and maybe Windies. And out of those three, it's only really helpful against Smiters.
Have a nice day and a 11k Blizz, here! Oh wait, you just lost 3700 life! Oh mi god!
Excuse me? Are you planning to actually hit something? max/ar/lifers, anyone? ar/lifers, anyone? torch, anni anyone?
No it's not, otherwise mcm would be losing his duels.
You do realize that you will need 9-10 perfect 5 all res lifers simply to replace the boots you swapped? Good going. Now, that means you lose 180-200 AR before multipliers, equal to ~1053 - 1170 lost AR. Not to mention the lost damage.
You do realize that with the best gear in the game and building in with bb and an elded storm, you are talking about ~93 base dex? Do you realize that this means you lose ~440 life? No, I don't think it's worth it, not even if you have perfect items.
No, the sorcs will just laugh at your puny 6100 life at lvl 99 or your 5800ish life at lvl 90. And you will be dead in 2 blizzards due to no ravenfrosts. Oh and wait, you're not going to hit anyone except some druids and sorcs because you have no +ar from charms, meaning ~7500 ar with ravens or ~5000 with FCR rings. Good luck.
