Inflated Prices
Mastery provided Ves with a first-hand perspective on how mech pilots handled a specific mech type. It was immensely valuable and he considered it worth its hefty price tag.
Even so, Ves already possessed a Mastery in landbound knight mechs. Would he really be able to gain as much benefits when he acquired a Mastery in its spaceborn version?
After some contemplation, he decided to add Space Knight Mastery I to his list.
"Spaceborn mechs are vastly different from landbound mechs. The three-dimensional aspect of moving and fighting in space as well as concerns about vacuum, inertia, momentum, flight, heat management and more add a lot more complexities to the equation."
In general, mech pilots found it harder to pilot spaceborn mechs. The barrier to entry may be higher, but they were paid a bit better than their landbound colleagues.
