How they would work and how would you use them?

(Green Bar represents Mech Height)(Red Bar Represents Weapon Height)
=(Raise Arms)=
Raise a Mechs Arms, Decreasing Speed & Passive Heat Per Stress & Stability,
the -20% Speed Penalty per Stability & No Heat degeneration per Arm Actuator Stress,
i feel these would help balance having Higher Weapons, or arm would be up 100% of the time,
=(Crouching)=
Lowers Mech Profile reducing Radar Signature by half, but stopping all movement,
being Stationary will save on PGI having to do much with animating Crouching Movement,
as so would help balance the new 400m Detection Radius, Aiding Ambushes,
Poll Topic,
=(Vote)=
Thoughts, Comments, Concerns?
Thanks,
Edit- Concept rework
