I have to agree with you, archers are OP in this game.
The spear is a mystery for me. I never used it in any rpg. I don't know why it is buffed by Finesse, I feel like it's more of a Strength weapon. I bet the spear has a well built place for her in the game, but I don't know where is this place. And I'm not planning to go there in the near future.
The spear is Finesse to add more options to the game, it makes Rogues and Rangers proficient in them, and it allows for the existence of Finesse-based warriors, who have additional range. In fact, there's one class build called "Warden" which switches between spears and bows as their weapons, whichever is good for the right situation.
Technically speaking, bows should be Strength-based since it takes strength to pull back on the bowstring and hold it, but how many people complain about that in a game?
