Actually, I like the idea of the cloak being something you can hold in your hand while running cloaked but then that will depend on how it's implemented. Do I have to keep it in my hand in order for the cloak to remain active or can I just swap to a weapon and keep the cloak active so long as I don't do any attacks such detonating REs or stabbing with the nova knives? I would very much prefer the latter if it's possible.

But yeah, here are my proposed stats for the cloak:

Standard Cloak (can fit on all suit classes and tiers)
CPU: 350
PG: 80
Cooldown Upon Deactivation: 30 Seconds
Cloak Stability Rating while Moving: 4 (moderate-high shimmer)
Cloak Stability Rating while Sprinting: 2 (high shimmer)
Bonuses when fitted on Scout: -99% reduction on CPU/PG usage and a +3 Cloak Stability Rating for moving and sprinting.

Covert Ops Cloak (can only be fitted on specialty Covert Ops Scout or Prototype Scout)
CPU: 350
PG: 80
Cooldown: 15 seconds
Cloak Stability Rating while Moving: 10 (no shimmer)
Cloak Stability Rating while Sprinting: 8 (very low shimmer)
Bonus when fitted on Prototype Scout: -99% reduction on CPU/PG usage
Bonus when fitted on Covert Ops Specialty Scout: -99% reduction on CPU/PG usage with -25% reduction to cooldown timer

Skill Prerequisite for Standard Cloak:
Cloaking Equipment Skill Book Level 1 ( -5% reduction to cooldown timer per level )

Skill Prerequisites for Covert Ops Cloak:
Cloaking Equipment Skill Book Level 5 ( -5% reduction to cooldown timer per level )
Cloaking Equipment Proficiency Skill Book Level 1 ( -3% reduction to cooldown timer per level )

What do you guys think?

EDIT:

I forgot to mention that in order to train into the Covert Ops scout, you should have to train up at least one of the racial scouts up to prototype level first as a prerequisite.
