Kickstarter Update 11Edit
Yes, there will definitely be CC in Camelot Unchained and it will play an important role in the game. However, there will also be resists and I’m not looking to implement a system where you can CC a player for a year and a day. There also will be another important part of CC that I’ll discuss in detail in a future update. Like the idea we are kicking around for stealth, it is a little BSC. There will also be a limit on the number of buffs/debuffs on a player as per other postings.

No talk yet about PBAOE. As to CC, it will be significant but not in a crazy, I got CC you until your next birthday kind of way.

We will have CC in the game but it's not just about the CC if you want to stop the game from devolving into ZvZ so we will need to do a lot of different things. However, we are not trying to get rid of the zerg entirely, since it can be a valid way to play the game depending on the game's mechanics. We just need to be a bit smarter.

Moreover, while having lots of extended CC abilities is a tad bit controversial, we will certainly have some CC (as well as resists and ways to clear the CC) so that smaller groups can have a better chance at dealing with larger groups.
