Lieutenant Chandis had a complaint for practically every aspect of the Inheritor model. Much of the reason why was because its design had been tailored for what the higher ups thought what was best for the entire mech regiment.
The wishes of the individual mech pilots who would have to rely on these death traps to survive in space hardly registered in comparison. Every improvement needed to be weighed against more practical concerns such as cost and ease of fabrication. If either of these two factors became negatively impacted, then Professor Velten wouldn't approve of the changes.
Therefore, much of the complaints he heard from Chandis had already been echoed by the reports he read from the database.
Still, there was a huge difference between reading about the problems from a dry and succinct document compared to hearing it from a mech pilot who had to deal with the consequences on a day-to-day basis.
