In fact Glest needs more of everything, but we are very few people and so we are forced to focus at a time on one of two things that we feel most important. At this time tucho has made new objects so that the maps can be more varied, and we´re working on some units to enrich the gameplay. I´d myself would like to have more buildings too, because I always liked the "settlement" building aspect of these games, like in the settlers or in warrior kings, but making buildings is time consuming, so it could be better that we focus on the things that add the most to the gameplay.
As for the units you talk about, there´s a kind of "light magician" in the additional downloads section of our page, and the crossbow man is too similar to the archer, though it could be interesting. Pitch barrel carrymen? so that they´ll throw bombs?
