I like my build because I don't like masheing keys for the cm builds and just don't think archon would work well at mp5 without incredible gear or with the mf/dps tradeoff I like to run for drops
My biggest question concerns my weapon. I feel like I should consider a chan will with a socket.
I would then get a big int boost and increased att speed. Not sure that a 1050 dps chan will with a socket is worth the 100 mil though. Would I get a big damage boost from it?
I have about 100 mil in gold.
I realize I could upgrade some other non weapon gear instead of my weapon if I reduce my mf but I like finding drops so frequently from maxed mf (with my follower). If a huge dps boost could be had from a single slot change I guess I would consider that.
IMO, the Chant Will is not worth it for your spec. The attack speed might be nice but you can get that from a dagger with IAS. Also, the APoC is mostly wasted for your spec, so you're paying a ton of gold for something you don't need. My main recommendation is use a dps spreadsheet or gear comparison to see just what you get out of the weapon. I recommend the one on this site because I wrote it, but there are plenty of others out there that also work. Just make sure the spreadsheet or application is working correctly before making any large purchases.
I actually think you could gain a few thousand dps from switching to a Triumvirate. A normal one with about the same damage range as your current OH only costs a couple mil, or you could get one with 200+ int and you should see a noticable dps increase. If you do get one, when you upgrade your weapon you will need to find one with no elemental damage to maintain the high dps. A Zinumassa's Trail (boots) will also give you a decent dps boost, though you'd lose the resist on your boots unless you pay a small fortune, but versions without resist are pretty cheap now.
I'm willing to bet farming would be more efficient if you switched to Archon and farmed MP1 or so, since you could kill stuff much faster. You definitely have the gear for it.
