All I want is consistency. If there is an L&L article, then it should be written every week. We should be given advance warning when an article won't appear. WotC has a terrible habit of setting expectations and then falling short of them. Is a missed L&L article a big deal? No, but when a customer is accustomed to expect an article, and it doesn't arrive, it sets a perceived notion of failure in the customers eyes.
I think Mike's biggest problem right now is that he is discussing what is currently going on, which means he is unable to write an article during a time crunch since it can't be written in advance. I'd like to see the article morph a bit to encourage the reader be more a part of the R&D discussions. Perhaps something like this (this is just an example):
1st Monday of the month: Discuss a concept from a previous edition that seemed popular and perhaps may be what the design team is looking at. Solicit feedback and brainstorm.
2nd Monday of the month: Focus discussion on challenges R&D faces with aspects of D&D. For example talk about monster design challenges. Greater in depth knowledge about the challenges provides more transparency for players.
3rd Monday of the month: Mike provides playtest anecdotes. Gives concrete examples of how the rules are seen from R&D which allows readers to get more insight.
4th Monday of the month: In depth article about D&D Next developments over the past month. Talk about classes, design, next packet release, etc.
WotC has done a good job of soliciting feedback, but it would be nice if we could be included earlier in the design process. It might speed things up (though it may not)!
