Having more options is better than none. Personally I like rolling stats not for the nostalgia of it, but it makes it feel like a table top haha. As for rolling stats making the game too easy, it really depends on if you play with premade characters or a full custom party. Overall, I think they should probably lock the stats of the origin characters, unless you play them. If I recall correctly, in DOS II you could adjust all appearance and stat things the first time they joined you. Hope they keep this the way as is now, shadowheart etc have set attributes and so on. full custom party is nice and all
But I do hope we get to save characters as well, akin to Solasta at some point. Back to topic, hope they add all 3 attribute systems.
