By this, Percieval means, he asked for a feature request which I responded to him: Possible sure but not certain on whether it's something we'd likely do at this time, but will note it down as a request.
Which is par for the course with a lot of the requests we receive? Is said -suggestion- possible? Sure. Is it something we plan to do? We'll have to consider whether it fits into our plans or whether we can justify allocating the resources towards it at the present time. Are there other things we need to work on that take more priority? Most likely.
Single Player and the other game modes won't be forgotten, they'll grow as the multiplayer game does, however, our design/balance will be based on the multiplayer version of the game, and we'll be targetting fixes towards that mode (some of which will impact SP, some of which may not because those problems may not exist).
