not sure i understand the reasoning behind majority of the plants shooting in every or random direction, when fan plants literally shoot it to be collected in the machine
plant shooting in every direction is here to duplicate signal. the rafflesia if has stored 100 signals, will send 4 orb of 50 signal, so if with fan plant, you send them again in rafflesia, the rafflesia has now 150 signal, not only 100.
Cactus do the same, for 100 signal stored, he will send 7x50 signal. with fan redirection, it become overpowered.
and you use one fan to automatically send signal in the right receiver
