vandal is useless. too weak vs anything, even massed. and made of paper.
tarantula is overpriced and therefor also does not kill these fast planes.
phoenix is useless and has mostly not any impact on the game
funnyweb is a shaddow of its former self. one shield and paper drohnes, too easyly disabled for that pricetag
hacksaw. expensive and yet not really usefull. due to its short range it cannot prevent bombing runs effectively. most times planes succeed (but die then).
bertha. award for most unfun unit ingame.
sonar. too expensive. but sea balance is borked anyway.
dominatrix? never used, it somehow does not fit to the game.
who does know what quake is?
skuttle. no further explainations required.
