You know why people hate your off-meta picks?
Because they are so rare, that people always remember when they lose.
None remembers losing when they got someone like Mundo, Lux, Mf or anyone that it's considered meta.
But you know what they remember? The 5/10 fp jg TF.
Everyone expects that with a meta pick you will at least be decent by default. But when you play off meta? Well you are either trash or a God.
And everyone hates to bet on people they dont know.
