Hi Dumbvent,
I too, have noticed the above. I would like to dial it in and replicate it as close to the CS:GO feel as we can however, this may take some time.
As far as "not replicating" goes, it isn't a big deal however, it would be nice to have it as similar as possible to carry the same feel across from server to server.
Unfortunately however, you are correct. As much as we would like to bring back all the fun quirks AWP had, this is currently possible with the lack of plugins readily available.
Over the next coming weekend, I'll look dig deeper into the double jump and any further issues I may find. If you have any more concerns then please let me know.
Cheers,
Kora
