>>7291547Lego now more than ever is experimenting with a ton of different molds and colors. Some colors in particular affect the strength of the plastic. Torso splitting has been a problem in minifigures since their inception but some are more prone to it than others.
Lego is only in a small dip now because licensed themes aren't selling as well as they use to. Star Wars was their cash cow for well over a decade and now the license has been damaged and flooded with characters, settings and vehicles that don't appeal to customers.
Right now, Lego is offering the greatest value in terms of overall pieces per dollar, variety and quality. People seem to have this warped perception that Lego use to be a better product at a better price. Pic related is only 360 pieces and adjusted for inflation would have retailed for $130US. For the same price right now, you can purchase the Ninjago Destiny Bounty ship that has 2300 pieces.
