Skill has been buffed as follows:

Now lasts 30 seconds at level 1.
Gatling gun has 1.5 second cooldown. Attacks 6(?) times on 8 enemies for 208% damage.
Missile: Attacks 8(?) times on 12 enemies for 360% damage. Fires 3 missiles(?). Still 8 second cooldown.

Damage absorption now only procs on 90% Max HP damage.
Cooldown reduced to 80 seconds at level 1.

It is also reported that Robot Mastery affects its damage. It however does not get its duration increased.
At max level, its cooldown will last as long as its duration.

You basically have to be in the enemy's face for the bot to proc so that 3 missile launching is applicable to bossing only. Hopefully it's range will be increased.

At skill level 1, a person did combat analysis and showed that over a total 30 seconds, the bot contributed 22% of damage.

If the next skill they introduce for Mechanics is Siege Mode, which can be fired with homing missiles, that would be crazy since it would be paired with homing missile. But it's a popular idea over at KMS.
edit: turns out the Robot Mastery not applying was in error. Maybe the duration will also be applied.

Robot mastery still isn't applying.

However, with the increased rate of fire from recent changes to the 5th job skill, this summon contributes a fluent source of damage that requires no change to Mechanic playstyle/attack pattern.

In that case, Nexon's objective to not alter class playstyle is fulfilled.

If you take all the damage this skill does over its duration, it technically is one of the highest damaging 5th job skills in the game. Then if Robot Mastery applies, the duration will last longer than the cooldown.

It is no Paladin 5th job skill, which more than doubles your final damage output, or Phantom Joker massive burst damage skill, but relatively the Mechanic's 5th job skill is not too shabby (in it's current version).
------------------------EDIT Live Version

aaaaand now it's a rather bad skill due to a change out of nowhere. It now has a cooldown of 7.5 minutes (450 seconds). I still don't know if Robot Mastery applies to duration. I sure hope it does, because they are giving this skill the Heaven's Door treatment.

Nexon's not-so-subtle way of saying "we still remember how overpowered you were in 2011".

My other relevant complaint was how unnecessary it was to nerf Heavy Salvo's range by 50%. They've already taken away 4 hits away...

Come to think of it, why do the summons have cooldowns? You could only have one out at once and none of them have downtime with Robot Mastery and hyper skills.

The fact that all of our robots explode after one death while the cooldown is still placed on summoning them renders them fairly useless for many bosses; I've only ever maintained summons up for mobbing, which does not require much attack power. I mean, at least the reactivation cooldown for our 5th job summon has been removed, but it's still a huge hassle to maintain in any bosses that deal %HP. I'd rather they just have toggle auto-activation once it's destroyed because maintaining our original summons already means you're losing DPS.

Auto activation could also make them more tanky, which compensates for the movement inflexibilities they have.

@09080706l: These things are true, and it also looks like this bot has low range in comparison to other attacks... Mechanics are the one class that cannot make diagonal/parabolic movement while bossing. This inflexibility in combination with their large size should warrant stronger attack power or better defense. 5th job should accentuate their strengths or cover their weaknesses; this does neither, as with many classes.

I was hoping for a toggle-based system like Xenon's, where it wouldn't be necessary to time/mash homing missile and suffer DPS loss for ping.

The fact that this bot can literally last 1 second, being killed immediately by blocking a 50% damage attack, really makes me wonder how this could be a 5th job skill. But after our latest patch, it is clear that they want mechanics married to their summons, which is a pretty bad idea, and is especially ironic considering this skill has no synergy with Robot Mastery.

I would like a less clunky dash skill and a faster activation speed for the Gatling gun. The Homing missiles are flawed as they already are, and far too connection-dependent. When 5th job was announced, I was honestly expecting more of a barrage-type skill like Siege mode, because it's more fitting to the automation theme they have going on.

Looking at the sentiments at Insoya, it seems mechanic players also think this skill is quite bad.

Some suggestions and sentiments they made:
Remove defensive part of skill (so that it won't disappear)
Make it affected by Robot Mastery and Mercedes Card, reduce duration
Remove the skill and give back a rehashed heavy machine gun
Bring up the defensive part to proc on 90% damage so that it doesn't proc too easily
Who MADE this skill?
This is probably the worst of the 5 job skills.
----------------------------------------------------------------------------

IMO, there are worse or equally bad 5th job skills out there.
Cannonneers is impractical.
Shadower's is nostalgic, but using it 4 times and having a 120 second cooldown is dumb.
Fire poison mage is lackluster, and does the same thing as Megiddo (but more damage) in boss fights.

I am just glad we didn't get some long cooldown map attack. Who actually needs that?

Nexon wanted to give players the ability to take down bosses like Damien, but a lot of the 5th job skills do not help the classes accomplish this. Rather, it is the massive skill enhancements and overall damage buffs (and no cap) that are making everyone so strong.

The 5th job update contents are still underway and more skills are to come.

EDIT:

Mechanic's 5th job skill has appeared to been changed, so that the Gatling portion has 0 second reactivation cooldown.

I like your optimism, but yeah it's just... ^

Pardon my bluntness but this looks like complete garbage.
