Problem was a stance-enhanced basic attack was the equal (often nearly precisely so) of an at-will, but at that point, an at-will all the cheap/cheasy only-amp-basic-attacks-so-no-big-deal items and whatnot could add to. Then, of course, the nature of Power Attack meant that they were basic attacks you could upgrade to encounter-attack damage. All pretty whacked, really.
'Need?' Does a game need consistency? What's the payoff for the added complexity of making them arbitrarily different?
Sounds, to me, like the simplest, most consistent, lowest-overhead way to do that would be to just same structure. :shrug:
I just lost a post responding to this.
But thats ok because I've thought of a better response.
Have you noticed that the 5e warlock is built on very similar lines to the 4e class structure?
i sure have! It's straight up AED(U). The U is in parenthesis because you can pick all combat "powers", or mostly Utility, so the U is on a sliding scale.
Instead of getting powers every level, you get at wills, encounter powers, and some class features at level one, then some more features and encounter powers at levels 2 and 3, and various other levels, and at regular intervals, you can choose features that either give you new at wills, new dailies, or new passive features. Some have level requirements. Then eventually you start getting regular daily powers.
It is very much like my ideal 4.5.
That is, you get a feature, from a list. Of those listed features, some provide powers, some provide passive features. Some powers are new at wills, some are dailies, and some class features work via boosting basic basic attacks.
In general, many encounter and daily powers would be simpler and cleaner if they were more: "make a basic attack, this stuff also happens", with a general rule that only one power or feature can modify a basic attack at one time.
Each class has some class feature choices, like both 4e and 5e. Some are bigger difference than others, just like 4e and 5e. Including stuff like fighters all marking targets, with variants that use the mark to defend, to strike, or to control. And even lead if someone can think of a model for that. And stuff like your Surprise Attack that replaces Sneak Attack.
I'd prefer for most 4e powers to be non level specific, and if needed scale their damage numbers by level, with minimum level requirements where necessary. And be able to use the same encounter power as many times as you have encounter slots, like a simplified 5e spell slot, or how Ki powers work. You have X encounter slots, and Y daily slots. Or you have a resource like Surges, and encounter powers cost 1, daily powers cost 2, and some features spend Surges to different things.
Anyway, imo something along those lines would allow for essentials style characters and 4e style characters, and would run just fine. Most of the potential issues with hacking 4e into this come from things that is like to kill in a 4.5 anyway, like many sources of stacking bonuses. Building a 4.5 from the ground up with this, and some corrections learned from 4e and Star Wars Saga Edition, and you might have my perfect RPG.
