Thanks for your advice. I'm sorry for that AH style posting, that was the last one.
According to Mighty Belt, this is obviously not an endgame item. But I think that it will do a pretty good job for an Act III.
2mil is quite expensive for such a belt. Though this isn't really "the price check thread".
I'm interested in hearing how people are doing with this build since 1.0.5. Especially the sprint variant (as after all, anything that isn't running at minimum 40% increased movement speed is not going to be anywhere near as efficient as sprint/whirlwind). I still highly doubt it would beat sprint/whirlwind when it comes to clear speeds but I'm at least interested to see if it can come close or not.
No not quite as fast as WW/Sprint, adds about 15-20 min to a MP 5 act 3 full clear to me, but is very viable still. Wth 5% or more LS it really starts to shine in survivabilty, even with low AR and armor like I have atm. Right now my rend crits have ticked for up to 260k, bash crits for 600k and charges crit for 700k with no WotB and I'm still well short of my end goal for gear. Its also a very good spec against Uber bosses
Either way WW builds with OP are more OP than 1.0.4 WW atm so really the only way to go if you want go with absolute best spec available that is the way to go. If you love 2 hander, board as hell of WW, or don't want to change again when OP gets nerfed next patch (which anyone using it with WW knows it will) then this is very much a viable alternative.
I don't think 1.0.5 barbs with overpower are stronger than 1.0.4. Even though at MP0-2 it's easier than 1.0.4, I'm slower because I lose WotB much more often. Even with overpower momentum and even at higher monster power so monsters have more HP I still can't keep it up as I could in 1.0.5 (though when I played a bit in a group on MP4 I could keep come somewhat close to 1.0.5 uptime on WotB). Of course the coefficient nerf didn't only affect fury, it also affected life on hit, which I had to replace with lifesteal that is much less effective than what life on hit used to be even with quite good gear.
Getting the same healing as before is quite costly, and getting the same WotB uptime is virtually impossible (even with full attack speed crit gear and overpower momentum I'm not sure you can compete with a 1.0.5 barb that never paid more than 10k for a single item in terms of WotB uptime).
By the way, what is "act 3 full clear"? If you mean clear everything from start to finish including all dungeons (which isn't very efficient), even for sprint barb it takes quite longer than that. If you mean alkaizer run then I'm still not sure as I haven't timed my runs (only measured 30mil exp/hour in 1.0.4 but that was with whirlwind disconnects etc and didn't count the total number of runs).
What use does this spec has for ubers? I mean, the main skill here is just not use-able. Rend is nice but you can do a lot more damage if rend is not your only fury spender. For example sprint/whirlwind variant that has rend (where warcry used to be in 1.0.4), or even HotA builds that mix in rend. Bash/rend combo is simply not something I'd call optimal or even good for an ubers killing spec.
