One easy solution for developers is, to calculate max SP.

Say we have 10 mechs..take top 5 based on power and then add max possible weapon power to them. Then pair pilots and calculate SP.

This is not dependent on SP of hangar. Hangar should be, to decide purely what mechs we intend to take to battle.

Stops hangar manipulation forever.

Only way to beat this system would be start new account and strengthen just one mech. Don't think 326000 xp guys would do that.

Strengthening one mech issue can be solved by having varied maps and different battle setups where no single mech or weapon can be good at all arenas.
