Guild Wars 2

I play as an Elementalist, and was wondering why suddenly my moves/abilities have changed completely. I had 5 of them which i unlocked over time and now they are reset to just one, but are all different. Im level 6

Your f1-f4 buttons change your attunement (earth, air, fire, water). Each attunement has different skills you need to unlock.

Ohh its because of my weapon. So now ive changed my weapon back to what it was at before, but 2 spells are missing from my action bar

Nvm i got it, i must equip my offhand aswell

Skills 1 2 and 3 and decided by your mainhand weapon, and skills 4 and 5 are decided by your offhand, and normally other classes have 2 weapon sets to switch into mid-combat, as an Elementalist, your profession mechanic is Attunements, so you only get 1. Engineer only gets 1 weapon set as well beacuse of its profession mechanic, Toolkit.
