Cloak and Dagger, what's the catch?

Solution 1:

A few disadvantages:

It has less overall cloak time than the Invisibility Watch if you're running (6.6s vs. 9s).
Whilst cloaked, you cannot use ammo boxes or dropped weapons to recharge your cloak, you must decloak to pick them up. With the Invisibility Watch, you can pick them up under full cloak.

Solution 2:

The important stats on the three watches are:

Invisibility Watch:

9 seconds Cloak Time
Charge time (to full): 33.5s
Recharges 25%, 50%, 100% from small, medium/weapon, and large ammo boxes respectively.
You appear as a team-colored silhouette when an enemy player or weapon hits you.

Cloak and Dagger:

6.6 seconds Cloak Time (assuming you're moving the entire time)
Charge time (to full): 15.3s
Recharges while standing still (cloaked).
You appear as a team-colored silhouette when an enemy player or weapon hits you.
Rather than decloaking, you appear as a team-colored silhouette if you move when the meter has run out.

Dead Ringer:

6.5 seconds Cloak Time
Charge time (to full): 16s
Recharges 25%, 40%, 40% from small, medium/weapon, and large ammo boxes respectively.
Does not cloak when activated, but the first time you take damage after activation (right-clicking again before being hit will put it back away).
"Perfect" cloak for the first 6.5s. After that, you appear as a team-colored silhouette when an enemy player or weapon hits you.
Can only be used at 100% cloak.
Decloaking at > 40% cloak remaining reduces cloak meter to 40%.
Louder decloak sound

Solution 3:

It does have slightly less charge, but I personally wouldn't go back to the standard watch - the Cloak & Dagger has saved me too many times where I would stand still and people just walked on by.

The less overall cloak can be mitigated if you stand still.
