Help with Skills ATA lv 120

[LionL 7]

Hello

 

I've been looking at some builds, and they all focus on high levels, which isn't my case.

I'm level 120 and have 60 points for tiers 1-3, Throwing Mastery, Windy, and Triumph of Valhalla are already level 10.

 

I plan to play only PvE, and I don't know which skills I should level up in tiers 1-3 anymore. I see some people recommending Split Javelin and Fire Javelin, and I really don't know if both are necessary, just as I don't know what the ATA's 1v1 skill.

And in my ignorance, I don't see how Soul Sucker and Shield Strike could be useful to my play style.
