I'm agreeing with a few points here, and disagreeing with others. I'll address some/most.
Keep in mind- MF character, I am keeping MFing in mind as well as some general PvM play
I am switching to Doom, and using a might mercenary. I am totally in agreement with this. I'll not have as much CB as I initially wanted, but with Doom, Beast, and whatnot it's prolly overkill and MFing im prolly gonna do 1 player most of the time.
whirlwind does not trigger life tap? I thought it did, I may dump a few points in frenzy or concentrate against bosses but I like War cry (I made a singer in 1.10 he was terrible) Maybe war cry is overkill for stun if so then points in frenzy or concentrate?
Griffon's +fcr ammy= bad idea, griffons offers nothing besides 25 fcr and 1 skill and my FCR needs are met by arachs, wiz/hoto on switch to reach 110% FCR. Hoto instead of double wiz because of the extra 3 skill for prebuffing, I'd use another Hoto but i need 5% more FCR. since i switched my amulet maybe I could use a FCR barb ammy, with skills and good stats, but on ladder a good barb FCR ammy is surely VERY hard to find. if i can get my hands on one then 2xhoto it is. You might be on the right track, there are barb circlets that can get godly with FCR- i had one nl, mods would probably be 2 skill, FCR, life/mana, 2 os for topazs/ums +str not needed cuz of torch, anni, and enigma
Guillames- I need shako for +2 skills, mana/life and 74% MF. I don't have MF weapon switches, so this is a little change in barb tactics meaning I can't load a good portion of MF on switch, meaning I have to use shako, enigma and gheeds and war traveler for good MF over 200%. (228ish% with those 4 I think?)
The Merc NEEDS insight. Teleporting without it is going to be near impossible otherwise. I'm going to be pumping vitality and maybe some strength, with 1 pt. per energy only a singer benefits from points in energy. I am going to not have a sorc's warmth or high mana pool, so insight is essential for the teleporting i'll be doing in PvM and MFing. Any BvCers know of how many constant teleports they can do in PvP before running out? The merc's insight means gaze is essential for LL. I might have him wear Guillames, but he'd die quickly which is no good.
I'll not wear GF items at all, I know GF is helpful but I do not find it profitable seeing as when I MF in hell i find items that sell for 35k all the time, and once I reach max gold amount in stash and max in inv, i gamble until my inv is dry and then do more MFing to fill it up.
I'm relle looking foward to this build, it's relle unique a few months ago I posted about a BvC doing MF and everyone laughed at me, now that I have ladder acces to better gear it seems more feasible and possibly a fun MF build, I might write up a guide for it and see other ppl's opinions, but maybe i should play it first before writing a guide but it'd be a change from all the cookie cutter stuff
