I'm still here, I'm just not as hear as I used to be.
I'm conflicted. At first I really loved the idea of bounded accuracy. However, they bounded it too tightly. At this point, as noted there isn't all that much difference between 1 and 20. Also, you necessarily end up with armors that have almost nothing to differentiate them except for fluff. The armor class difference between light, medium and heavy armors is practically nothing. Who cares if you get 12 +5 for dex, 15 +2 for dex, or 17 +0 for dex. You're still at 17.
3e was too excessive with bonuses, but in my opinion 5e is too weak with them. A middle ground would have been nice I think.
See, a lot of what the pro bounded accuracy people are saying is what I was trying to say to my player, but more and more my player is convincing me that the 5E skill system is simply too simple to model characters especially well. There's little growth in skills; sure, your proficiency bonus goes up from 2 to 6, but it's difficult to get new skills (Spend a feat on skills? Yeah right). Expertise is linked to only 2 classes, and multiclassing into them to get better skills feels odd.
I'm beginning to wonder if the skill system could be expanded. Maybe to have 4 ranks of skills, instead of the binary of trained/untrained we have now. What if there was untrained, proficient, focused, specialized? Untrained is no bonus, proficient is proficiency bonus, focused is double proficiency bonus, and specialized is auto advantage (or switch focused and specialized?). At certain levels, you gain more skill "rank", either to gain proficiency in a new skill or to gain a new level of proficiency.
Yes, DCs would need to be adjusted a bit, or at least higher level characters would be going up against hard and very hard things more often. General checks that are going to be applied for everyone would be aimed at the proficiency level, but things that only one person needs to do could be aimed higher as the levels grow. This way, the characters will feel like they can accomplish things they couldn't accomplish before, instead of just being marginally better at what they could do before.
I don't know, I'm still looking at a massive overhaul, but I don't like relying upon Rule 0 to make me like a system. Oberoni Fallacy and all that.
