Forum:Questions about Spectre Training

Hey, I'm still pretty new to this game and I'm really enjoying it so far but I had a couple of questions about Spectre Training. Specifically, I'm kinda confused about the percentage increases to accuracy, damage and health. Is it best to raise spectre training earlier or later to get a higher bonus or does it not matter? I know it's a dumb question and I'm probably not doing the math but I am currently leveling this talent up and it feels like I should be getting a bigger bonus to my health besides one measly point.

Any help would be appreciated. -Thanks.
