Unfortunately they did the patch notes for the weapon re-balancing in the most aggravating way possible by not listing any of the actual number changes they did to the weapons, which is a completely mind boggling thing to do.

Spear primary attack can actually pump out a lot of damage during a stagger, but the alt attack is complete and utter garbage holding it back. Damage for THROWING your weapon out of your inventory + having to go retrieve it/risk losing it based on terrain is simply not worth it; if it auto returned after 6-8 sec and the weapon range being 2M instead of 1.8M it'd be fine.
