I actually think he commited on two things.
1.) The trinkets will be looked at.
2.) He thinks it's a good idea to announce player-made tournaments on website and launcher.
This is more than I expected to get. Also we have a direct answer from him regarding PvE gear, which is at least something we can quote when it turns out to be wrong.
Compare it to any other developer interview during the last days. I would have loved to ask more things in detail and stay on certain topics (did that for the trinkets, which cost us 3-4 other questions). We had 18 minutes and 37 seconds for this interview and audio problems. This was the best we could get.
Thanks for the effort, I think you did a great job with the limited questions and he probably screened/prepped for the questions you gave him.
For a serious constructive discussion, follow up questions are where you can really dig in. His reactions to your initial questions about growing the pvp community and increasing accessibility were concerning. I feel as though he doesn't have any long-term plans for the pvp scene, as evidenced by his references to Starcraft and other games for "pvp fixes". It would have been nice if you could have followed up on a few of those points.
