Re: Can I just buy every Skill that arrives? or is there a limit?
Buy every skill, it is generally worth checking the trainer for new skills every couple of levels. Differences in build boils down to choices in trait setups, you will get a quest to earn your first trait at 15 and gear choices.

Buy them all.
You can also see skills you can't learn yet, but (un)checking the box.
They have removed most passive skills, but be sure you check out that tab as well.
You should be able to buy a skill every 2 levels ( on odd numbers)
Some will be new, while others are upgrades of previous earned skills.
You can find a complete list of your skills in the character panel, skills.
This is where you can take them from and put them back on your quickbar is you happen to remove one by accident.
