CCP Seagull posted the summary of Oceanus changes coming at the end of the month. This blog isn't intended to entirely about lvl4s/burners but it's quickly becoming that way. Anyway, in case you missed it here's the blurb on burners:
New Burner Missions, now with logistics
Take on a new set of Level 4 Burner missions with more high powered enemies in frigates which have brought their own logistics support. A dev blog is coming with both information on how Burner missions have fared so far and the details about the new missions.
Sounds like some of us are getting our wish for a more complicated encounter that all but mandates you bring a friend (or five).
Looking forward to the additional details....
Separate but related topic, there was some news about lvl4's in the last CSM Townhall. You can get the full mp3 of the conversation here, but I'll attempt to transcribe the part at the end (about 48:20) about CCP's efforts to rebuild their in-house dev tools (I don't know who the speaker was; I am bad matching voice coms to character names):
Something we are now pleased that we can talk about... CCP are working on PVE tools that was [announced on] the [alliance tournament] stream. Basically, the problem at the moment is that the tools that they have are less than intuitive, and so they are a bit of a pain to make changes with. Which is obviously going to slow stuff down. They are working on the toolset at the moment, which is going to make it easier for them to add additional content and make changes for other things with it.
So, on PVE content: once the toolset is back into play, and has been redone, it will be far easier for them to add new stuff. Don't have a timescale for that, but they are working on it at the moment.
This jives with things that we have been told before. Investing in a new toolset is a signal to me that CCP wants to continue to extend PVE and breathe some life into decade old content. Which, if you're a reader here at all, should know that I think is a big friggin' deal. See also my Manifesto.
