Complaints are like cockroaches, you see one that means there is 100+ more you aren't seeing. And even if you don't see one there are probably still many there.
Most people don't report their issues due to being conflict averse (and are even less likely to say anything when responses to ideas/criticism are dismissive/hostile) as such they either avoid the thing that causes the issue or just complain to friends rather than making things known to the creator. This is a flaw with human nature but is one that needs to be accounted for.
This mod clearly has a mathematically provable balancing oversight and therefore it is a problem even if no one has noticeably spoken out about it.
But I'll put my hat into the ring and say "I'm another complainer for this issue"
