Ves only possessed a sparse amount of experience with heavy mechs.
Heavy mechs generally tended to be a mech type that only showed up in military mech regiments. Only military mech designers or those working for a company that serviced the military became exposed to heavy mech designs.
Heavy mechs were big, expensive and put an enormous strain on a mech unit's logistical capacity. They also only truly unearthed their potential in major battles and campaigns.
For these reasons, hardly any private outfit wanted to put up with these costly elephants. It was practically impossible to run a mercenary corps at a profit by fielding heavy mechs!
Not just the end users, but also the mech designers experienced headaches whenever they came in touch with heavy mechs.
