SUGGESTION: Make side-quest additional skill points account wide (per league)

Problem: Playing the campaign again in a league for a secondary character feels too slow.

Solution: Remove the need to complete certain side quests that you have already completed on a different character in that league. Especially the ones that give extra skill points.

Once the quest has been completed and granted the player skill points, those skill points should be automatically available for any newly created character to spend.

Why it works: This not only speeds up the campaign by removing the need to complete side quest each time you go through the campaign within a league, but it also provides a skill point base level for subsequent characters, which raises their power level and speeds up the early campaign progress in a way which tapers off until they reach endgame.
Because that system would be league specific, the side quests and associated bosses will be experienced at least once with the new league content and remain optional for other characters to complete for item drops or possibly even other rewards that don't feel as necessary as skill points.

Please consider this change, I truly believe many people would greatly appreciate it and it would be a good solution to the "I don't wanna do everything again on a new character" feeling, also allowing for more experimentation and overall satisfaction.

Addition: This could also apply to other side content rewards from bosses like spirit, life and resistances, not only skill points.
