Ok, so if they aren't terrain, then why do they need to be impassable like a wall or building? Doesn't Lilith have a terrain marker(forest) that she places and gets bonuses for running or attacking into it? All I am saying is that if it acts like terrain, and has terrain traits, then shouldn't include the other basics of terrain , such as, cover? Or am I really being unreasonable? From a design point, you create an ability which creates "terrain" markers on the board. They are solid, as I cannot move through them, I cannot see through them, but I can shoot freely through them if I can see part of you without granting you cover, just like every other solid piece of terrain does, be it temporary or permanent. And as a disclaimer, i am not B*tching or moaning, but just trying to understand the design theory, preferably from a designer and not a fellow "end-user", like myself.
