Been wanting to league start Wild Strike for a few years now telling myself I'd play it after melee buffs, but I'm giving up on that wait after tonight and just going to have Frost Blades as a fallback and Ice Shot or TS as a contingency. The plan is eventually go omni TS, but I want to fund it with this doing low essence farm start into red legions with exarch altars. Going off poe.ninja I couldn't find somebody who did what felt right during Crucible, so I made my own pob https://pobb.in/tVvK_z6Z7Gz5 for once instead of using a guide.

I'm new to actually fully fleshing out pob's from scratch but I think I did a good job keeping gear very conservative for worst case scenarios. I'm a sc six portal enjoyer and I know the pob reflects that. I also haven't played strike skills for a few leagues now, and while any input is appreciated I have the following questions specifically:

Is Ghost Dance worth using over going armor/evasion? On real gear I can imagine that es being doubled and I don't think I can squeeze in determination, but possibly discipline with a 2 node reservation small cluster and 30% reservation shield.
Is just the 1 extra strike from attack mastery good enough for clear? I prefer to run Kaoms Spirit as the pob does now or Shadows and Dust in the glove slot so I won't get more there. It'd be nice to not use ancestral call as a link, but if I do what link should I replace? I might play with good rare gloves later but I won't plan on it for day one gear.
Fun annoints? There's always the reliable Divine Judgement for budget but surely that's not the best choice, at least once using golds is an option.
Does anyone actually have experience with which Combat Focus jewels make it feel better from previous leagues? I'm currently planning on using none but I can see myself blocking fire if the aoe is too small, and I might be convinced that focusing on just cold hits with Heatshiver.

Again this is just day 1/2 gear and I didn't pob any better gear other than an all T2 mod claw which adds 20% damage. I don't know how much phys claws go for but that's my first planned major upgrade, probably within a 2 div budget. Further upgrades will be winged depending on where I feel like I'm actually lacking in legion clear. Also celestial leap slam is more fun than whirling blades for movement, I will forever die on this hill. Thanks in advance.
