Guild Wars 2

I’m only level 40-something, but aren’t all skills supposed to be unlocked in the Mists?

I’m a Ranger, and I don’t have Water Spirit, but it is available for purchase for 25 skill points. I only have 17 skill points, though and I don’t know how to get more in this mode.

The new skills need to be purchased, no matter what mode. Maybe the skill point scrolls drop in PvP, or you can purchase them with glory, I’m not sure as I don’t PvP.

Edit: From December 10th Game Update Notes

Profession Skills

We are introducing a new healing skill for each profession. These skills are locked in both PvE and PvP. They can be unlocked by purchasing them with 25 skill points. When a skill is unlocked on a character, it becomes unlocked in both PvE and PvP.

Also you can buy Tome of Knowledge for glory, that gives you one level. If you have already lvl 80, you will still get one level and additional skillpoint. It means, that you can unlock this skill (and many more that will come in the future) playing only in PVP mode.
