Reading the new summer topic made me thing about the problem with iceflingomatics. They are pretty strong stopping fires and a cheese machine but a blackhole of resources to protect a base, even an small one
What i suggest is to change the way of how iceflingomatics consume fuel. If they dont waste fuel or not that much when they are on but not throwing ice and making them waste more fuel when they are throwing ice. In this way, unloaded iceflingomatics will keep their fuel instead of being wasted for nothing and the player can see how much fuel they are wasting since fires on screen (not enterily true but that is other topic) so there is more control on how much fuel the iceflingo needs since you are seeing how much is wasting when is trying to stop the fire
Also this will balance cheesing since the player will need an interaction to refuel the iceflingomatic to keep the permafreeze on a boss which with the system we have is pretty cheap since those builds doesnt waste fuel for being 24/7 throwing ice
