Best skills to unlock first — new player picks

This gets asked a lot, so here's a starting point for new players deciding where their first points go. My take: a mobility skill first (Dash is cheap and always useful, Teleport is the stronger panic button later), then Emergency Heal — instantly healing all your cells turns a lot of losing fights into escapes. After that it depends on your style: Stone Skin if you keep dying to burst damage, a projectile like Frost Shot if you like chasing things down, Cleanse if roots and slows keep getting you killed. Veterans — what would you tell a day-one player to unlock first, and what's the biggest waste of early points?
