More opportunities to change how our skills work and interact with each other. Maybe we can work with powerful NPCs to unlock thematic variations of our skills. Lorath for instance could teach a rogue how to make sigils, unlocking new Horadric variants for each of their trap skills. Taissa could teach a druid how to draw upon the power of the swamp, putting a regional twist on their earth skills. I feel like blizzard nailed it with the world building this time around, and I’d love for them to lean into that by making it a bigger part of our character progression in lieu of adding new classes.
This is the approach I take. I can roll with character deaths and dice rolls that fundamentally alter the trajectory of the game - I just can’t tolerate losing my agency to quirks of the engine. I once lost 3 companions because they were standing on a trap during a cutscene - didn’t hesitate to reload in that case.
