Somewhat orthogonal to your rumination on published adventures but the general premise is in-line with something I've been thinking on (regarding PC Build Resource Inflation and the "arms-race" implications therein).
With respect to (i) 3e (including the multi-class rules and Prestige Classes) <snippage>
Boy, that is an awful lot of power for a single class feature and an awful lot of room for intra-feature power imbalance (especially if they decide against augmenting specialties and using this formula for other powerful features...features that don't count as another space-occupying creature).
I tend to agree. The only other solutions available (I think) are to "stretch" all that extra stuff out over more levels...which folks seem loath to do, or to drop companion critters altogether...which folks are even more loath to do. I suppose that they could theoretically duck Narrative, and do something like FATE or BW, but those types of games are generally "not D&D" and lack the space for all the fiddly bits necessary for producing good splat.
Due to the feedback loop of adjusting one aspect of PC build resources and how that affects PC output versus expected monster output versus total encounter output, the quality control effort will need to be extraordinary (for what effectively seems to be a small business - a small franchise of a large corporation that must make a case for its earning potential and legitimize its expense ratios to its shareholders). Bounded accuracy will help them a bit (as they will not have to deal with the 2nd and 3rd order functions of to-hit percentages) but there are so many variables beyond "to-hit" that I'm hesitant to hope for each system (core and the various customized iterations)...especially without group ii having to fiddle with the default assumptions of monsters and/or the encounter formula.
I agree here as well....its one of those nagging bits that floats in the back of my mind. Such an effort is very costly. Costly at a a level that only initial sales of a new edition can support. I keep thinking this is the "farewell" edition and it will be shelved after some initial rather small run of product. Putting out a game that is modular, well-balanced, and customizable to playstyle as well as with a zillion fiddly bits is literally not worth the effort, I fear. Who knows, maybe they'll get the electronic stuff working well this time

.....what? It could happen!?
