I typically farm with TR on MP0 - Act 3, the Kaho/Alkezier route. Ideally I need closer to 100k so I can just sprint through it all without as much doubling back and passing over mobs twice as I do now.
I've been in the same conundrum with my gear "what do I do/change, changing any one piece gets rid of things I need and are hard to find" for 2-3 weeks, and I think I finally figured it out tonight after rereading your post, what you search for in the AH, and using the d3up calculator. I'm a bit ashamed to say I didn't even realize a calculator like that existed, which is probably half my problem.
My current gear, while it has the stats I need, has them on the wrong items. I concentrated too much of my vitality on my pants so I could get double resist, movement speed, and a good bit of dex on my boots, I have a cheap and high damage amulet, but no real resist or vit, etc etc. as you went over in your post about the tradeoffs of each slot of my gear. I finally came to the conclusion that the only solution was to just regear myself in most slots to reorganize where I have the stats/etc that I need. This is what comes of just building off what you've found to be good while playing without using google-fu!
I'll post up my regear tomorrow once some auctions finish, I think I've kept my EHP about the same (~375k) and gotten up to 90k DPS or so with about 6-7m, some of which I should be able to recoup by selling off old gear. Still waiting on a few of the auctions to end however, so I may go a bit over that estimate if some of them sell for more then I expect.
Thanks a bunch for the help, it made it all finally click for me!
i started using and tweaking the tr build (to my liking) for a couple weeks now so think i could chime in on this.
im running with 290 loh/942 lps (my only sustain) 400 resist (could be higher but works so i dont wanna bother upping it) 4k armor (could be higher but once again works so dont matter) 38cc (would like this higher but dont have a hellfire with cc) 365 cd 46k hp and 114k damage
low 30s crit was pretty !@#$ty much much better close to 40%
4 piece innas is very useful for the sweeping wind reduction (allows you to spam sw between fights to keep your regen up)
get rid of overawe rune (shouldnt be spamming anything besides tr) and put in submission its great for cleaning up leftovers with little hp left.
drop seven sided for the air ally he is also great for cleaning up scraps and with the templar and submission plus if you ever run low on spirit he can randomly fill you back up. im actually at a toss up right now of using the ally of blazing wrath for damage bonus since my spirit seems to be fine
now for gear
not sure about your budget but a skorn closer to 1400 damage would help quite a bit and they are cheap as hell with dex and any random mod thats not ls. mine only cost 4 mill on a buyout which was prolly slightly overpriced. this would also help with your hp since you could get one like mine or even higher vita to make up for the armor lacking it
get rid of your oculus ring for a unity. this will give a big damage bump along with crit and a small amount of loh which is all you need for mp0. not sure about prices but you could prolly find one with your single resist or vita or socket or something of that nature for fairly cheap
change your belt for innas with vita or life% (pref vita since you have low hp)
change your chest to innas with 200+ vita this would help alot with your hp issue and changing the ring/belt but this might cost a bit
change your helmet for higher vita or life % instead of the armor
if you made these changes it would keep your hp decent along with bumping your damage up quite a bit. your kinda stuck with the way you geared that you cant just swap 1 part and call it good. all the upgrades i suggested are fairly cheap except the chest but that can be used outside of the tr build also. when i swapped i already had a decent balanced dw gear setup. all i had to do was swap my ammy/helm/weap/gloves which cost about 7 mill total for all
quick video of it. even with the frenzy shrine able to keep tr goin without running out of spirit.
