I will only respond to you if you post video proof from his PC with the warp speed shown.

Cringe, on the off chance this friend actually exists, and you are somehow unaware of his blatant lying.
>no video or screenshot... at the time
You said yourself he has tested this more recently, why has he not taken a SC since then. You've never even seen proof yourself so why are you believing this obvious false hood.
>It got nerf-ed
The trait was never changed, altered or nerfed in any update since release. Neither has any trait, item or set that affects slip stream/SST speed.
>Some of the details I don't remember
What a surprise
>Colony deflector/disco def
Neither affect warp speed in any way
>all the other items you listed
I used them in this build, look at the wiki for info on my build
>doing doughnuts
You are aware doing doughnuts decreases your warp speed right?...
>legendary miracle worker assault cruiser
This ship doesnt have access to the chroniton integrated slipstream which is the only reason and way to do donughts in slip-stream, and to surpass the warp 100 mark.

and i was in a discord call at the time the build was in-use while i was in-game seeing him doing donuts in slipstream at warp factor 300

like i said there was no video nor screenshot made of the build because he was busy doing tour of the galaxy at the time

Preferably a video for obvious reasons...

Which you will now link if this is true obviously

Or linked a video?

So he showed you a screenshot?

so it got nerf-ed :(

im on a discord with him now and he just told the build is now doing around warp factor 260 not 300 now
