But why 6 saves and not just 3?
More variety.
1 is a lot simpler than 3.
For the simplest, roll a d2. If you roll 2 you win the campaign. A 1 means you lose the whole campaign.
But.i definitely wouldn't consider that D&D. You want some complexity.
5e already had problems with 6 as in they needed to make 3 uncommon because distributing spells becomes bit annoying.
That’s easy enough to fix. You would have to redo all the saves if you went to 3 anyways.
side complaint: i really don't know how you use Dex to dodge AoEs. The whole room is filled with fire, how does a quick side step help with that?
Also do we need really small +1 increments on saves? This just comes from the stats. But if we want to make it from new why not just +0 +4 or +6 to saves (bad, mid, good) or something like that.
Yes. It allows you to get slowly better over time.
5% (+1 on a d20) is a enough to be noticeable but still small enough to feel like gradual improvements.
10% improvement (+2 on a d20) would feel slightly too big of a jump IMO. Doable, but a little big.
I.e.
5%: bench pressing 200lbs one day and 210lbs the next.
10%: benching 200lbs one day and 220lbs the next.
Also if your never going to have an odd number, then divide by 2. Make it a +1 on a d10 roll.
Also why do players need +4 to hit?
Going along with the +1 growth, yes.
Why not start at +0 to hit? Makes the start simpler and combat slightly faster.
+0 is when your not proficient in it. A peasant throwing a stone at a dragon gets +0, or a fighter trying to cast fireball.
Which avoids negatives / penalties.
You want people to feel positive about their characters power. Penalties feels like they are disabled.
The idea of removing stats should include the advantages of it, which is making things simpler not reintroducing the bad designs stats bring with them (especially the too many 5e saves).
There is certainly useless complexity in D&D, ability scores to ability mods for instance, but if you remove all the complexity you remove what makes it interesting
Again, flipping a coin is very simple, but that's not fun for very long.
