Freezing Pulse CoC with Molten Strike (now with video)

After playing a hard-hitting CoC ranger in the last league and being guaranteed to oneshot myself against ele ref anything, I wanted to make sure to focus on survivability and ref immunity. This focus guided my choices in the following ways:

1) Using a high crit life-on-hit claw instead of a dagger, as would be typical in a standard CoC setup. Because I'm generating tons of tiny hits all the time, my effective regen rate is quite high, even if I hit an unlucky streak and go a long time without proccing any casts.

2) Redundant mitigation. Instead of focusing on any one defensive approach, I diversified to ensure that each time I'm about to get hit, that hit has to go through multiple hit checks. With Grace and Tempest Shield, I've got 40% evade (before flasks), 53%/67% block(/spell block), and 40%/45% dodge(/spell dodge).

3) Taking Freezing Pulse over something like Flame Surge, which packs a lot more of a wallop, means that the damage I take from reflect is much easier to partially mitigate (since it comes in lots of little instances of damage) and doesn't trigger block animations (since all the individual hits blocked are quite small). Also, with Freezing Pulse's high base crit rate, most non-unique mobs are frozen when in melee range. Also also, because I'm running a death-of-a-thousand-pinpricks build, it benefits a lot from Herald of Ice.

The playstyle is pretty straightforward -- get into groups of mobs and MS at them until they're all dead, which tends to happen really quickly. The more mobs in the pack, the more procs you get (since each of the little balls has an aoe component, so it has lots of chances to proc); the closer they are to you, the faster they die (because Freezing Pulse shotguns with GMP/LMP).

While leveling, I used Lightning Warp + Curse on Hit + Assassin's Mark + Elemental Weakness with a Doedre's Damning. I've since had to switch it out for a resist ring*, so I now use Lightning Warp + Curse on Hit + Assassin's Mark for in-combat movement and Whirling Blades + Faster Attacks for general movement. Lightning Warp is great for in-combat movement because it can move you while you're still attacking -- that is, you can cast Warp into a group, then start swinging wherever you are, and you'll land with 2 of your free swings from Multistrike still in the queue. It also has a more predictable/reliable/useful aoe for purposes of Curse on Hit.

*"If you're hurting for resists, why not switch the Atziri's Step for a Rainbowstride?", you ask? Because I'm already very close to the cap for spell block -- I'd get more resists out of Rainbowstride, obviously, but I'd be trading 15% spell dodge for only 8% spell block.

The short of it is that I'm reflect immune, even in ele reflect maps, and can facetank anything that can't oneshot me (including, say, Palace Dom's lightning projectile stream). The big weaknesses are:

1) It requires a 6L (or 5L Voll's) to work properly, unless maybe you have a Romira's Banquet. I wore a Tabula Rasa for ages.

2) I'm lower on life than I'd like to be, so I'm vulnerable to occasional oneshots from some heavy hitters (say, Dom's lightning punch). In an ideal world, I'd be wearing a 6L Belly of the Beast or Lightning Coil to help mitigate this issue, but I can't afford them at the moment.
