Alright so, maybe i'm just understanding things differently or I'm just dumb but whatever, this is what i gathered from the testing.
1. These 'loadouts' also known as the 'A&B thing' are predefined loadouts that in no way shape or form represents the actual amount of choice we'll receive at launch. It doesn't mean a large part of the ability system will be locked for you.
2. For those missing abilities, you can find some in other specs or make sure to press P and check your ability list in the guardian section, you would be surprised at the amount of people who miss this. Thats for the abilities that are in the PTS right now. For those that are entirely missing, I assume its a bug or this is how the combat style would be on other classes combined with said classes base abilities, which would fill the in the said missing abilities.
3. This doesnt feel like a streamline. This just feels like we've received half of the class which I'm thinking was the entire point. No point getting riled up over it until we get the final unlimited version.
