It's a tough question to answer. I'm still "a customer" in that I buy almost every
Saga Edition product; and I've made a conversion of
Saga Edition for my fantasy games, since
4E's races and classes are so annoying for the most part.
- Redo D&D to be more like Saga Edition -- classes should be a toolkit, not a straightjacket. Multiclassing should be quick, painless, and infinitely flexible. In Saga, you build your character to a concept -- take a bit of soldier and a bit of noble, and bang, you've got an officer. In 4E, you are your role (thanks a yahoo, WoW), and anything you try to do to escape your role is doing it wrong.
- Fire the art director. Please, please, PLEASE get rid of all the flash-bang-noise, and get back to historical, classical, and other primary references, instead of the current cargo-cult-version of the fantasy genre.
- Stop making everything its own rule. A 1st level 4E combat has more mods, tweaks, and conditions flying around than a 13th-level 3E one. I thought the point was to SIMPLIFY playing?
- Of course, a print version of Dungeon magazine is required. But it has to support a good game first.
- Stop shoving tieflings and dragonborn down my throat.
- Talents are cool. Superpowers are not. If I wanted to play a superhero, I'd be playing Champions.
- Embrace open standards. The OGL was a great thing. Go back to being "a part of the gaming community" instead of looking at the gaming community as "your customer base."
- Un-screw-up gnomes. If you just don't get them, that's fine, leave them as they were and ignore them. Gnomes are an acquired taste. But don't screw 'em all up.
- Lose the delve format. I'd like my modules in a single bound softcover, please. Similarly, lose the "encounter" mindset. An adventure should be more than a collection of rooms with monsters in them!
- Did I mention to stop shoving tieflings and dragonborn down my throat?
Note: These opinions are mine alone. But you did ask.
