The weapons in CtC2 are pretty genius, it seems natural that they should keep a couple. Ice is really tactical for over one shot castles. Fire too but, like others have said, burn time should be quickened a bit. You could clear some room in the shooting options by taking out the wood logs.
One small thing about the builder: it's often impossible to place a piece exactly centered where I want it. It goes a little to the left or right of the desired spot. To illustrate this simply: you can't place something at the exact center of the screen.
It's always a little to the left:
{"t":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"l":["tg","mg","bg","wc","id"],"r":["rw","rwc","rs","rsc","ri","ric","rb","rbc","rfb","rpb","rrb","rf","rl","rr","ra","rp"],"n":"","c":["bwd,540,660,0.5,0.4,0"],"o":-1,"":""}
or right:
{"t":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"l":["tg","mg","bg","wc","id"],"r":["rw","rwc","rs","rsc","ri","ric","rb","rbc","rfb","rpb","rrb","rf","rl","rr","ra","rp"],"n":"","c":["bwd,545,660,0.5,0.4,0"],"o":-1,"":""}
It's more of a problem once you start settling. Things move a tiny bit making it hard to align new pieces exactly. Obviously pieces have to move in intervals. I guess what I'm saying is if the intervals were smaller it would make the builder more fluid.
