When setting up my defenses, I've found it frustrating to try to assign particular pawns to a task. If I want Joey Jabroni, my best builder, to set up a turret, chances are Bob Jablobi of skill level 4 has already taken the task. To get Joey on the task, I have to right-click on the task, find out it's taken, pause the game, find and recruit Bob, go back to Joey, give Joey the task, unpause the game to let Joey start working, and remember to unrecruit Bob a couple minutes later.
My suggestions are thus:
1.Let players override current task assignments through right-click prioritization.
2. Let players reserve a task for one pawn exclusively.
As things stand, I have to limit the number of pawns assigned to construction to only the best if I want the important things done quickly. However, that's sub-optimal when the only thing to do is lay down some power conduits.
