I do not understand why so many players call lemurs, galagos, angwantibos, pottos and lorises low tier. Is it because they're "less diverse"? Lemurs probably make up like 60% of larger mammal diversity on Madagascar. "less widespread"? Lorisoids have around the same range as catarrhines. "Less big"? Less than 1000 years ago we had lemurs the size of gorillas. I've heard people argue its the nocturnality which causes them to be low tier, but nocturnality is the basal state for mammals (which is why a lot of them have a tapetum lucidum). They aren't "wasting points" by being nocturnal, other primates spent points to be diurnal. In fact, owl monkeys are an example of something which had to "waste points" to become nocturnal.
It's not like strepsirrhines are boring either, some lemurs are capable of digesting poison, lorises are the only venomous primates, pottos can bite down to the bone, and galagos are basically living springs. I feel like a lot of the strepsirrhine underranking comes from people not understanding them.
