PoE Berserker, League Starter, Slam builds

From what we've seen so far, do you guys think zerker with rage and impale would be a good choice for 3.19? Here's a quick pob I threw together (not sure if I'm calculating the dps of it correctly but it looks promising). Perhaps the new buffed chieftain node will also make fire conversion good, but I doubt it will change a lot. Doesn't need anything special, just a decent axe. I think it will be a good league starter and ssf build, but I'm worried about defences. But then again defences are getting gutted so may as well go full

I dont think i took too many liberties with the config, weapon may be a bit strong imo. Idea behind this, both tectonic slam and war crys are supposedly getting buffs + support gem so we want to take advantage of that. I like going crit and your options are Swords or staves, i have always liked the idea of staves and they give us some end charge and power charge generation which is important. Tect slam will now use 1/3 the charges, meaning we can now use someone other than Cheiftan and Jugg. War cry buffs mean more damage and once you take the instant warcry node
