I have been experiencing a few issues since the latest update when Blackwood DLC was released on the Xbox One. Did not experience these issues before the update.
Few of the issues I have been experiencing:
#1 Unable to cancel heavy attacks or experiencing delays in activation of heavy attacks.
#2 Instant abilities taking 2 to 3 seconds to activate, having to press repeatedly.
#3 While walking, sprinting or on a mount my character slows down for absolutely no reason, even coming to a complete stop.
#4 Having to clear game data cache on my Xbox One console or even restarting console in order to use zone, guild or group chat.
Note: I tried checking my internet speed just in case and I am currently 228 mbps with 0% Pocket Loss
I only play on the Xbox One, because it is cheaper then PC.
