There have been a ton of issues as of late and have been progressively worse since Harrowstorm was released.
1. Stamina morph of blastbones isn't working. The skill will just grey out on the skill bar and am unable to use until I bar swap. This has been a consistent issue in all content to the point that I do not play the class anymore. Crystal fragments from the sorcerer's skill line also has this issue but is less common.
2. There is a issue where you are unable to use skills at all and has been getting a lot more common as of late. Basically any skill you use will start an animation but then quickly stop without going off. Then for some reason it starts draining your stamina even though the skill is a magicka ability.
3. You cannot use R2 to rapidly dismount. After creating new character the hints still say either L2 or R2 could be used but it isn't working correctly. After making an off-cycle PTS to make the game more "intuitive" then have an issue that contradicts the hints in the leveling up process is extremely worrying.
4. Extreme lag spikes and disconnects are at an all time high. It is almost guaranteed that in any trial you will have at least a few disconnects.
There are many more but this is what comes to mind thinking of major issues. With the Greymoor chapter coming out are any of these going to be even addressed? I have a tough time justifying keeping my subscription and paying for this new chapter when you can't even quest in low populated areas anymore.
Here is a video showcasing the first two points I made.
