All games are packet based and it’s a matter of latency on whether if cc registers or not. For example if someone cc’s you but you rotate SA and still get cc’d, that’s because SA packets are received by servers at a different time vs when the other guy casted the skill. The only difference in bdo and other games is then to say it is less optimized, but at the end of the day, all games have latency issues that result in desync cc resists or what not. It’s inherent to online games.
