PoE builds similar to Path Of Exile 3.22, Wilma's Ice Crash, Shaper Full Fight

I'm running an Ice Crash Berserker, and focusing almost entirely on Grand Heists. The build is of course rage-based, which makes it poorer for bossing and their downtime. I've integrated a lot of AoE radius nodes, and have it up to 39 units. I've got about 1 million DPS, and am wondering what tweaks or substantial changes I might have overlooked. The PoB (linked below) has some of the obvious changes integrated, such as maxing gem skills and qualities. Several changes I'm considering and would appreciate input regarding: 1.

I wanted to play around with Warcries and Ice Crash was just pretty, so I've been working on this build since league start. Nothing fancy yet as far as equipment goes, Ideally a + crit chest and a ring with frostbite on hit would be a better choice, but I've only put maybe 2-3 Ex worth of currency into this build. Handles T16 just fine, and while single target isn't great, with a little work this could get up to 1m Shaper DPS pretty easy, at least according to PoB. Let me know what you think, and any suggestions.
