Ender did my build in an hour yesterday. He explained to me what savings he could probably have achieved if I wanted to take him longer, but I was happy with a quick turnaround. I was even more impressed by the kit Ender got me. It's not worth me talking about the improvements Ender made to my Barb - let's just say my Barb was an example of all the gearing mistakes listed in the first post.
Played for a few hours last night - this build and gear is fool proof. I'm generally a defensive style player, so DWWW is a big shift for me. So, yes, I was dropped by the first elite mob I encountered in Act 1 Inferno no MP. After a couple of hours though I took out two pairs of the Infernal Machine Ubers in MP6 after a couple of hours (and I farmed the keys in 2 hours). Am still learning how to deal with some elites, especially any combination of shielding, reflects and plagued (at least that's what I have encountered). My point: if you're new to WW and think you're experiencing "problems", it's probably your play style NOT the gear these guys got you - e.g. not dumping enough fury to keep WOTB up. Shielding has also caused me some problems for LS and the only (fun) solution I've found so far is to find more mobs :) I was playing for a couple of hours with a solid monk who died 3 times on one particularly elite mob (shielding, reflects, vampiric) in MP6 and I died once: more evidence that survivability is good and revolves around play style and NOT pure based on the gear these guys get you.
Having said this, this service is not for everyone. Could I have picked this gear set? Sure. I've read the guide. It's not hard to learn how to gear properly for particular builds, but it is time consuming learning the nuances of the AH market which change in important ways with each patch. If you think you know the AH well then feel free to gear yourself. I was happy to pay Ender 10% commission for his knowledge of the AH. Of course, their knowledge of gear is fantastic, but you need to know your gear too. There will always be weak points in a gear set, no matter your budget. But, these guys combine a nice build with great knowledge of the AH and this is what you pay them for.
Highly recommended. Thanks again Ender.
