Oh wow you really need some resistances. Try to craft a shoulder with all res, get some on...well anywhere you can. boots, chest, maybe belt? You could get zuni 3set for extra EHP. Work on armor too. Not sure what MP you plan to play, but EHP is a bigger concern now.
A better weapon will help a lot. I'm not a fan of EF for LS Archons. Once the prices go down a bit you should be able to find a high DPS wand with LS+OS or a decent dps sword with LS+CD+OS, depending on budget.
I totally agree with needing more armor/resists. If you want to run higher MP you need more armor and resists or you'll kill yourself on RD mobs, even with a LS weapon, or just get torn apart by high damage mobs/elites. Zuni chest will give you a ton of mitigation, and the 200+vit versions should be cheap. I saw one 264 vit with 30 some phys resist for 15 mil earlier today.
As for what to craft, I'd start with bracers. You don't need the extra MS since the cap is 25% from gear. IAS is nice but char sheet dps matters more, and you can get higher dps with crafted bracers, in addition to picking up resists and some combination of vit and/or armor/str.
Mempo helm, with 200+int and some vit might be competetive with your current helm, but will offer more resists and you only lose near useless life regen.
For Witching hour, I'd try for AR instead of vit, but that's just me. Either way it won't be cheap, so might be worth waiting.
Also, if you dont mind the loss of a little vit, you can swap your rare ring for a SoJ. That will greatly increase your elite dps, and you can get a 30/6 for a couple mil or less as long as you're not picky about the random wiz affix.
With all that said I'd start with the weapon, or at least start by looking at how much dps you can gain from each. Weapon, SoJ and bracer is mostly dps gain, chest, OH, and WH will be mostly EHP gain while keeping dps.
I went from CMWW to Archon (for fun). So I got a Lacuni, Mempo (253int, no crit) and a Chanto MH (1050,socket) and OH. I like to bring my Chanto set for some gay elite combos if I panic (I just stunlock them CMWW style). Also I find it 100x faster to reset Archon with WW instead of LL or anything else I tried. But probably its stupid? Tell me why :).
I find it hard to find upgrades to my gear that don't cost a fortune. So if you got some nice tips where I might have not looked yet for (relatively) cheap upgrades I would be thankful. I guess somewhere around 30-50 mil per item if it actually improves dps or ehp by any significant amount is what I am looking for.
Yea, I just got a zuni's chest with 178 int/261 vit/35 phys res/74 all res, that raised my ehp by a load. Gonna wait a few more days for things to balance out before I get anything else (as well as the fact that I dont have any more gold to spend, I like to keep a buffer for repairing and such. ) Thanks everyone!
Quick question, would it be better to go for a ruby or emerald in my weapon? (either would be marquise) with 50%+ crit chance?
OP you're officially the first person I know who's got a weapon with a gem in it that's worth multiple times more than the weapon -- so yeah, upgrade your weapon oh and yes *definitely* get a mempo, some nice rare bracers and shoulders with AR/armor/life% lots of room for ehp improvement there, same goes for your witching hour
