Sorry guys, was really busy the last months thanks to housebuilding - but WotC overall already started to gather informations from the community, the biggest issue seems that they (see our discussion here) aren't able to rebuild MTGO (yet). At my freetime i write some articles for the german marketing agency. Last year me and other were interviewed about "Media Perceptions Magic". I only knew about some answers from italy. But we shared the same view, that WotC digital products aren't good enough.

According to my opinion WotC needs to address three points:
develop a cross plattform app (as lemnear pointed out, you can't even play the casual "duels" on android(!) or PS4), massiv decrease to buy into competitive MTGO (i feel sorry for players that need to invest several hundreds or thousands to get digital(!) cards), graphic/visual rework of MTGO (any "competitive" mobile card game looks better... even the casual "magic duels" game looks better than MTGO)

At least i can say, the agency send all the feedback to WotC/Hasbro.
