Adding those 2 new companions to this game takes as long as it does exactly because it's nearly impossible to integrate new characters into an already existing campaign with this editor. Aside that, what I was thinking about is the expansion that is going to come. A better stream-lined editor makes everything happen faster. And time is money in game development. When you occupy your map makers and scripters for 6 months on 1 map because the editor has flaws then they are not making new maps for other things in your project pipeline. Meaning everything takes longer.
They will use this editor for years to come
Ah ok, I see what you mean now and that makes sense. I'm beginning to wonder how well an expansion or further projects they work on will do considering the mess this has been since release. There's still time to do damage control, but they need to start showing some results like fixing the numerous serious bugs in the game and toolset.
