That set is something to strive for when your growing your toon. If you are weak it will definitely be a good start. However, once achieved and you want to grow past lets say 150k DPS, you will need to let it go. You cant have full set and achieve really high DPS.
To be honest, I didn't have any intention of going 5 piece set originally. I was running 3 pieces already when Ender helped me out with some free gear ( at the time he said my gear was sorry.. so he tossed me free gear ) One of those items happened to be the IK Helm which put me at 4 piece.. so I figured why not and got the other 2 pieces to earn the achievement for completing a full set ( lol )
Love the 5 piece IK set. 2 of my 5 piece dropped for me. I'll be looking to changed the setup (ice climbers and Menpo) to move past mp5 speed runs. I can survive easily up to mp8 (build change) but mp5 WW skorn and IK set is great for speed and I cannot even do perma WoTB.
Hell I can't do perma WOTB during Alkaizer A3 runs. I don't know why but i generate too much fury when I don't need it - but too little when I do need it.
I even tried running Boon of Bul-Kathos to lower WOTB's cooldown, but it didn't seem to make much of a difference.
Random topic :
I have two barbs at level 60 ( I was leveling a second one when Blizz decided to announce Paragon Levels which sort of killed my second barb ).
One might ask why did I want 2 Barbs?
The answer was : WW farming on my main, but I also wanted a second Barb to I could mess around with other builds
Anyways, I am not a super rich guy - I have maybe 200 mill at the moment. I want to do some sort of 2-H build that doesn't even use WW. Like I want to be able to 1 shot whites at lower mp levels just by Bashing their face in or Cleaving their head asunder. Is there a strong 2-H build that could be done with 200 mill that would be able to farm at least Mp5 easily ?
