Cossack Engine Boost Consumable

Should be renamed Engine Brake. While it does increase Cossacks top speed as normal, it severely reduces acceleration. Here's some testing results:

 

Without Engine Boost activated

#1 Stopped to 31.6 knots: 6.98 seconds

#2 Stopped to 31.4 knots: 7.56 seconds

#3 Stopped to 31.7 knots: 7.46 seconds

 

With Engine Boost activated

#1 Stopped to 30.4 knots: 12.31 seconds

#2 Stopped to 30.3 knots: 12.16 seconds

#3 Stopped to 30.1 knots: 12.35 seconds

 

Is this a bug or intended behaviour?

Further testing, this time to see how deceleration and subsequent reverse movement is affected:

 

Without Engine Boost activated

#1 ~30 knots to Zero to -10 knots: 14.57 seconds, then 19.40 seconds (total)

#2 ~30 knots to Zero to -10 knots: 14.84 seconds, then 19.68 seconds (total)

#3 ~30 knots to Zero to -10 knots: 15.17 seconds, then 19.96 seconds (total)

 

With Engine Boost activated

#1 ~30 knots to Zero to -10 knots: 13.82 seconds, then 16.35 seconds (total)

#2 ~30 knots to Zero to -10 knots: 13.45 seconds, then 16.10 seconds (total)

#3 ~30 knots to Zero to -10 knots: 13.42 seconds, then 16.22 seconds (total)

 

So it seems Cossack performs slightly better at slowing down and reversing with Engine Boost Brake switched on. The unusual behaviour of this consumable - probably due to the interaction with Cossack's inherent acceleration buff - makes me very hesitant about fitting the special module (+50% duration). It has some use in crossing distances (higher top speed is always nice) and slowing down to plant smoke, but you certainly wouldn't want it active when it's time to leave again.

So can anyone explain how this would happen? How do these things slip by so many people in the initial stages? Is it that super testers don't actually test? Surely that acceleration in the first post would have to be noticeable to anyone with more perception than a lump of goo?

Given Cossack is the only ship that has both speed boost and the RN special acceleration characteristics, definitely seems like a bug - I’d submit a report if you haven’t done so already.

I have never seen anyone else report this, that really would be a question for WG.

Generally, I will accelerate to near max speed and then kick in the speed boost when I have a hand free. I wasn't aware of this "bug" (and I'm happy to call it that) but have done this instinctively.

For comparison, a Benson with Engine Boost activated in both cases:

 

Without any Propulsion modules

#1 Stopped to ~30 knots: 12.76 seconds

#2 Stopped to ~30 knots: 12.83 seconds

#3 Stopped to ~30 knots: 13.02 seconds

 

With Propulsion Mod 2

#1 Stopped to ~30 knots: 10.54 seconds

#2 Stopped to ~30 knots: 10.58 seconds

#3 Stopped to ~30 knots: 10.90 seconds

 

This appears to be working as expected. It's interesting that Cossack under Engine Boost is almost the same as stock Benson under Engine Boost, almost as though the consumable is "overwriting" Cossack's inherent acceleration buff and making it perform just like any other ordinary, Engine-boosted Destroyer.

I think you misunderstood...

He says the ship accelerates slower *with* Engine Boost, compared to without.

This isn't about Propulsion Mod.

I misunderstood... myself? I'm the only one doing the test results so far. :Smile_Default:

I tested Benson to see how a typical Destroyer compared to Cossack's bizarre performance variations. As mentioned above, unmodified Benson is almost exactly the same as Cossack when both are under Engine Boost. Additionally, when Benson adds in Propulsion Mod 2, it gets even faster - so Engine Boost isn't overwriting that particular buff. Cossack, though, appears to completely lose her special acceleration buff when Engine Boost is activated.

With Update 7.10 I have re-tested Cossack's acceleration under Engine Boost to see if the listed fix (something about turning speed) also affected the raw acceleration issue:

 

With Engine Boost activated

#1 Stopped to ~30 knots: 6.42 seconds

#2 Stopped to ~30 knots: 6.82 seconds

#3 Stopped to ~30 knots: 6.87 seconds

 

Cossack is now a dragster. With Engine Boost active, she accelerates even faster than normal - and "normal" is already ridiculously fast. This ship is a shell-dodger's dream.
