Keep/Add
Campaign Components. These are great. Best Dragon idea ever. I'll leave it at that rather than gushing.
Ecology of X. Not as an every month thing, but perodically.
Class combos. Great idea. The early articles like this inspired me to do these for my character, who isn't a "pure" concept.
Alternate/added rules. I don't think I've seen anything like this since 3E was released. I thinking some of the very old Dragons that had rules for pain, weapons wear and tear, weather generation and so forth.
More focus on character/world development. The Wizards' Workshop section is nice, but it always feels like an appendix (maybe that's because I never read the fiction, silicon sorcery, and FR stuff). I guess a lot of this is actually taken care of in the Campaign Components, but I'd still like to see something of plausible geography, religion, or politics in a fantasy world.
I get the feeling that I'm in the minority, but I like to hear Gary Gygax spout off about the early days of D&D. I wouldn't cancel lose sleep if his columns were dropped, but they are far more interesting than anything in my "Drop" list.
Drop
Fiction. I never read it, so it's wasted page-count to me. Contrary to what I may have indicated elsewhere (heated discussion and all), I'm not completely opposed to having it in the magazine. I would be much happier, though, if it wasn't an every-month thing. Maybe include it the months that have Campaign Components (which I'd like to see every-other month). That way, the issue would probably appeal to both crunch-heavy and crunch-lite types. My favored solution, though, is to get rid of them.
Silicon Sorcery. Blech. I want this gone, yesteday. No uncertain terms and no real sympathy for those who like the column. Don't care about the games (okay, I do, but not when I'm in D&D mode). I really don't even see a correlation between NWN and tabletop D&D, unless you're doing an article on running a DMed, group game in NWN.
Speaking of NWN, I'm sick of the imports from the game. The ones I've seen aren't particularly inspired. Just say "No." Don't give me _any_ imports from NWN. Oops, too late, how about "no more"?
Change the artwork. Okay, this is universal for me in 3E, but Dragon covers are the worst. I have yet to see one that I like since the change in format. Stop making them look like PC Gamer. The old-style covers with full artwork and smaller lettering were _much_ more attractive. At the very least box the artwork in -- I hate reading in someone's armpit.
