TRUE, we just based our work on etpub version, but it has never been our intention to become the next version of etpub or successor of it. Please stop naming our mod as the etpub continuation or so, it has never been meant to be so.
cg_damagekick is just a kind of built-in no recoil hack... Keep in mind no single mod but ETPub has this.
I don't get why all ETPub servers should migrate to silEnT. AFAIK silEnT was not meant to be a replacement for ETPub and what is more, I think variety of mods and their features is only a good thing for players, they are free to choose what they like most.
Any change on server would result in few players complaining. It's up to the admins what to tell them. Upon each ETPub version update on my server from 0.7 to 0.9 players use to whine about hitbox change when ETPUB dev team use to tell there is no change in hitbox. My question made years back still stands. Which modes beside ETPUB uses to disable damagekick? There was a reason why we removed it on the first hand and we still haven't found reason to add it back. If you have any specific reason to add it back please feel free to share and we will look into it.
