Another update for LoD Cold Twister.
After playing this build both in solo push and speed, I am much happier with the Channeled Twister playstyle, now that corner stacking is allowed, and we can ping pong combine / redirect twisters. So much more control, it feels great. I also liked the increased freedom of rune choice. I was having fun! 
In my solo push feedback I mention Valthek’s straight line behavior still feels bad.
I tried this out in solo speed, and while the straight line is still problematic there, it’s not nearly as bad, since targets die quicker.
Solo speed had issues of slower movement (no room for Aether Walker), but was still regularly clearing the rift in 3.5-5m time with wormhole and illusionist. Feels about the same clear / pace as what channeled Meteor shower used to be at.
One other downside is the sheer number of multipliers we have to fit in. LoD can accommodate these much better than DMO, thankfully, and at least we have some choice in our build with LoD.
Wicked wind is still somewhat underpowered, could use a slight increase to rune weapon% damage, I was thinking 1150% would work well.
In Solo push, I managed a GR132 in 12m 43s @ 10.7k INT with ~125 keys. This was a double festering though, so I was lucky there. Should be able to complete ~GR139 @2kp with full ancients/augmented/proper affixes and extreme fishing. Level of damage / build power feels good.
