Exactly, it was a literal translation from the tooltip. I was testing "if" character size had any influence at all. I think it would be nice to create a niche to use this trait with small races, and was simply suggesting the viability and prospect of coding logic.
No discrepancy, just providing feedback on how it could be better implemented, otherwise colossal slayer is the clear choice and no reason to take giant killer at all. horde breaker is...ok, for an extra attack, but bad at single target engagements (obviously)...but it is often better to just focus a single target down faster, so again colossal slayer is better out of the three choices you get upon leveling.
"IF" giant killer worked as some have suggested it should/could, it would create some variability in ranger builds to provide choices and balance.
