There seems to be plenty of demand to justify having a third option on character creation. That also wouldn’t conflict with anything that they said since the 1.14 version would be preserved.
Classic, LoD and LoD+/Blizzmod/whatever you want to call it
Item and skill changes or new content would be confined to the new mode and leave 1.14 alone for people who want to play untouched(ish) D2.
I think the main reason they may consider not doing that is a fear of competing with themselves for D4, but I don’t think that actually is a real issue. I’ll try D4 regardless of D2:R having an extra mode with changes or not. They’d be completely different games. New story, different combat, different abilities etc. We’d still be getting A LOT more new from a D4 than some rebalancing or minor content additions in D2:R. Being able to play an old game in a slightly different way is an entirely different thing than a whole new game.
