With the TR changes in 3.14 AoE investment is not attractive anymore, since it spreads the pods even more reducing single target dps. If you don't invest on AoE and get an anomalous concentrated effect, you can reduce the radius of TR from 14 to 13, increasing the overlap rate from 4 pods to ~4.8, causing almost all of your casts to overlap 5 pods.

edit: overlap rate is actually 5.4 if you use anomalous conc. effect (14-19% quality) as further discussed on this topic

The bad news is that the the area is so small that aiming becomes difficult and that's where ballistas come in. It's auto target feature is amazing to counter that. They have a downside that you cannot pre-fire on bosses like regular TR, but they catch up on dps once they start shooting while also making you safer, since you don't need to stop to shoot.

For Clearing, I didn't like the idea of weapon swaping, so I'm using Caustic Arrow on a Wyrmsign, making it a 5 link, still gaining the dmg from my main weapon while also enabling Rampage. We do need endurance charges generation for it, which can be done with Elder Boots affix (which I recommend since you can get Increased duration from Elder as well, which is great for TR and IC setup), The Red Dream unique jewel, veiled ring affixes or even Enduring Cry.

For instanced bosses I swap Wyrmsign for a DoT rare gloves with a Frenzy + despair on hextouch setup. Using a despair gem for cursing is a big increase since it gets a nice boost from quality and I have a lot of increased despair effect from the Cluster jewels. This setup DpS is around 50M (no vaal haste/blood rage).

Defensively the builds feels pretty good. I got IC on autocast with 70% uptime (1.36cd and ~3s duration), Winddancer (20% less dmg), Anom. Dread banner (4% less dmg), Ghost shrouds (9% reduced dmg) recovering full energy shield on hit, High evasion/spell dodge, Blind on hit, Taunt on hit from the totems (10% less dmg), lots of slows from TR, Hinder and chill, Ailment immune and lastly and most important, free movement to dodge while the totems do their work (they are pretty tanky with 9k hp and capped resistances).

The build budget is around 100ex, but I crafted most of the items. It should cost you ~150ex if you are buying. Crafting is really easy for most of the items. I recommend Remi's guide to get nice crafting tips.

The build is scalable from league start, actually one of the best league starters out there. I recommend Asmodeus guide for leveling.
