Please consider adding something similar to what Diablo 3 has - “adventure mode” where players can level by doing bounties / rifts rather than going through the campaign for each new character. This can be accessed by new characters as long as the account holder has beaten the campaign at least once.
Most players (maybe not most, but a significant amount) don’t care about stories in ARPG’s and I am one of those players. I would like to be able to level my new characters without having to go through the campaign every single time. Make it optional if players want to go through the campaign or the new way.
