Size OCs will forever be a love it or hate it kind of thing, they are simply very self indulgent and cringey by nature, and in the end also nothing but a vessel to project their creator's ultra specific size tastes and kinks; I personally am quite fond and a very big fan of a bunch of them but I also easily see how they could be a sore sight for others if you don't vibe with whatever hyper specific idea or scenario they are bringing to the table.
And frankly, the real problem with Lajest's OCs isn't their gacha knockoff designs or their "cinematic universe" ass lore, just the sperging schizo behind them.
