Sinkhole missions need higher payouts

I am not sure if anyone gets this, but I get a ton of sinkhole missions like significantly more than others. ( I have gotten over 15 of them today) and each of them only pay between 1-3k and they eat up a lot of resources (15 pieces of apparatus not including ambulances and not accounting for rescue engines and quints). Considering that many other missions that require up to 15 pieces pay upwards of 5-8k or higher depending on the mission, these need to pay more if they have such a high frequency.
