If you want to just invent rules on the fly, all editions of DnD up to 3.5 are about the same. The advantage of 3/3.5/Pathfinder is how much stuff is built in so you don't have to houserule every little thing.
If I was going to houserule Pathfinder, feats would be the first thing to get out. Level based attribute progression would be next, along with prestige classes and the skill system. It doesn't have the advantage here because it isn't really alike to the game I would like to play. It is not that I find these to be bad fetures, or that I would never play a game with them. I would, I did, and I would again. But they are only useful for a very different style of gaming, one that I find fun, but not the one I would be looking for in PE or that is my favorite.
Using your example, if a character wants to make that attack and doesn't have the power attack feat, you could quickly rule that he has an addition -2 to hit since he's untrained. Nothing is lost, and speed and structure is gained.
Or I could rule that there isn't feats in first place, which is even quicker nd helps me not having to worry about feats ever again.
You're basically saying you don't like structure, but every edition of DnD I've played has been highly structured, you just made rules on the fly to do what you want.
Grunker is right, I don't think DnD is the game you're looking for, certainly, ADnD isn't better about any of your examples compared to 3E.
AD&D at least provides me with a lot of interesting rules that, even if I don't want to use, can still be used as food for thought. Like the section about NPCs in 1e. I wouldn't use that rules, specifically, but I think it is a good starting point to make your campaign a little more about managing other people. The weapons vs armor class table in 1e isn't very good either, I agree. But the idea behind it is sound, and you can make a good table from it. On the other hand, a lot of the stuff 3e provides with feats, prestige classes and what not are about how you can bend the rules in certain ways than about some aspect of the world. Of course, 2e isn't perfect, nor is 3e completely awful. But I still feel 2e beats 3e in this regard.
