played a two-weapon fighting ranger and noticed several issues regarding ranger abilities and two-weapon fighting abilities:

1. Taking two-weapon style at lvl 2 is pointless: right now, for all characters, ability modifier is added to damage roles on off-hand attacks, but not on attack roles. this is supposed to be the other way around. i believe this is a bug rather than a design choice, since this makes the 'two-weapon style' that rangers (and I'm assuming fighters) can take pointless, since ability modifier is already added to damage roles.

2. Colossus slayer applies even when opponent is at full health: it's description states that it doesn't apply when the opponent is at full health.

3. Colossus slayer doesn't apply when using hunter's mark: If you use hunter's mark, you don't get colossus slayer damage.

4. Colossus slayer damage is not added when making off-hand attacks: If your first hit of the round is with your off-hand, you will not get colossus slayer damage. Also, if you make an off-hand attack first, and main hand attack second, colossus slayer won't apply to your main hand attack either. (I was using the Loviatar dagger in offhand that Blesses on successful hits, so I was making my offhand attack first)

4. Colossus slayer damage added to 'knock unconscious': didn't verify this, but if so it makes this Action essentially unavailable to you.

5. Colossus slayer damage doubles during critical hit: don't think this is supposed to be the case?

6. ''Dual wield'' feat does not add AC bonus: It states in the description of the feat that an ac bonus is added when dual wielding, but this isn't the case.

7. If you are toggled to ''dual wield'', you will use up your Bonus action and take an offhand attack even if you kill a target with your first Main hand attack. So it's best to keep the toggle to ''one-handed'' if you don't want to waste your offhand attack unnecessarily.

Hope this is helpful for all those considering playing a ranger! Dual wielding is not useless in this game, but if I knew 'two-weapon style' was useless I would've taken another one.
