I don't know if anybody will help me, but if anyone could...

I'd like to know if I am right by banking my skill points for when I need a certain skill, or if by doing that I am missing out on extra skill points (or levelling up faster) that could come with a new action?

Those are the skills I already have:

Survival Starter Kit; Backpacker; Boosters; Haggle; Crafting Expertise

Dodge; Health Regen; Vault

Stun; Kick stun

If you feel like it you're welcome to suggest what else should I get that I don't already have :)
