PoE Double Strike builds

Hello everyone, So I've came up with this pob in about an hour or two, its a very basic 2h impale champion build, I'm using double strike because I want to use something different of molten strike, lightning strike, boneshatter, you get the idea. I'm looking for any possible improvements I might have missed/don't know about, also, this is meant to be a mapping exclusive build, just to make it clear. Thanks in advance! &x200B; pob:

6.5k life gets you 754% attack damage with a single warcry node and the battlemage buff effect implicit on boots. It forces you to be a 1handed build but for solves all your increased damage needs, allowing you to spec life and crit only on the tree ect. I messed around with double strike got 15m dps and you can pop THE BOYS for an extra 5m burst. Thought it was an interesting interaction that can be used on pretty much any melee skill, maybe someone will come up with a good build with it.

Purely theorycrafting at this point, I am fairly new to the game, but have a few hours in. I know there are a lot of zerk builds out there, and probably a lot of health/armor builds out there. I am looking to try something new, on paper looks pretty good except the damage numbers. Any thoughts are appreciated. POB:
