A previous server I played on capped the homunculi levels at 250, and at that level, they were able to MVP pretty decently and kill effectively in Biolabs 3.
But as for now, with the cap at 200, my Vanilmirth doesn't do so well in the deadly dungeons.
It would be nice to see a higher level cap for homonculi because it would give people who use creators as their main a way to MVP.
