Okay let's go.
First, it's slow. I hate the fact that the attackers (assuming the number of attackers is less than the number of defenders) run in, kill the defenders, then wait a minute for the defenders to come back in to find the flag only dropped to 180, then kill the defenders who in that time will have boosted the flag up to 210, then you just have a little bit more idling around the flag, then kill them, then wait, then kill them, then wait, then probably die a few times. When there are more attackers than defenders, the flag still ticks over so slowly, it just starts earlier as soon as there are more attackers than defenders.
It think KotH reduces the advantage defending has always had. In my opinion, it's meant to be easier to defend than to attack, and if the speed which the flag decreases increased with the ratio of attackers:defenders (which would please me otherwise) it would throw out that balance even more.
It's quantity over quality with KotH. It allows large groups to control forts while small ones struggle. If KotH was meant to allow newer guilds to take forts (as some people have mentioned I believe), it certainly doesn't serve that purpose as they have no chance against large groups of defenders.
On top of all that, Castle and Snow were two very basic yet unique forts, and now all the forts are complex because of how the way you played at Castle and Snow has changed.
One of the most enjoyable parts of Graal in my (and several others's) opinion is defending or attacking forts in small groups and still coming out on top. This doesn't happen with KotH. It's so frustrating you're defending and there's just a few more attackers than defenders who just run around the flag while it drops. Same goes when you're attacking, trying to kill the hordes of defenders and by the time you've killed enough for the flag to start dropping they're already coming back.
I have no opinion as to whether KotH should be featured on the FB server (I don't play on facey). I feel like the lower overall playercount might cause problems.
tl;dr
I want my sig back
