[Method T]

For reference material. Crushing Iron (Metal's Stun/Four-way Beam) has a 28 second cooldown. The skill itself lasts two seconds, and the stun is only active while the beam is. This means, it gives a player .5 seconds to react and follow-up with a second skill, if the target was right next to the player when the skill was used.

It's good, because it is a stun, but it's honestly one of the less impressive ones, its biggest saving grace comes from the fact that as a 4-way beam it has a wide enough range to be fairly effective, especially against melee.
