I think pve-c servers are populated maily by people that are more interested in building but like the occasional pvp experience or people who like to troll/hunt these or newbies who want to try out all mechanics bar raiding.
Regarding the pvp hours on pve-c servers (and this is my personal play experience), I log in during pvp hours, not because I want to pvp, the hours are at the time, I usually have time to play. I personally would prefer 2 smaller windows per day instead of that long one during my main playtime. But it is what it is, I can manage and the pve-c server is what personally suits my playstyle the most, as I don’t care much for pvp, but don’t want to completely miss it.
I guess what you are looking for, is a pvp server without raiding
