Haven’t seen this quite suggested in the dozens of respeccing posts.
Gain respeccing items from bounties/challenges/bosses:
Much like Ichor, I’d like respeccing to be meaningful and a challenge to gather. I think the watcher serves as a good person to respec from.
Limit Respeccing points to 1-3 points per item:
I’m not a fan of full respeccing in a souls like multiplayer game, I think it dilutes the experience of honing a build over time and building a relationship to your character. I think full respeccing would also impact trading items between players, players being less inclined to trade / items carrying less “OOO I need that”
