No, not quite. That makes it out like there was a falling out.
Dave has some personal issues to sort out that are more important to him than the running of Maveryc and MDS. He has taken a break from Wargaming, sculpting and the internet.
Be assured that as soon as Dave is ready, there are no hard feelings from myself, nor Mac. Speaking for myself, I am more concerned for his wellbeing than anything else, even if that means Maveryc is shelved forever.
And yes, I cannot imagine any other sculptor working on Pax Bochemannica. Dave was actually helping me get better at sculpting and I finished 6 more halflings in 'his style'.
