List of annoying things that would be nice to see fixed:
1) The glitched arrow that appears stuck at the feet of a character when wielding a bow. When using many class skills and ultimates while your character has a bow drawn will cause the glitch to occur. Also, swimming while the bow is drawn will also cause the glitch. (These issues are confirmed on both Xbox One and PS4).
2) Dragonknight's Spiked Armor and its morphs clipping through a sheathed shield while One Hand and Shield is equipped. If Spiked Armor or either of its morphs are active while a shield is put onto a character's back, the spike animation clips through the shield. (Confirmed issue on Xbox One).
3) Restoration Staff sometimes forces the player to activate a heavy attack before being able to perform a command (such as looting a body, talking to someone, or opening a door). For some reason, while a Restoration Staff is equipped, sometimes the player will be unable to perform talk, pick up, or open actions until the player holds down the attack button long enough to perform a heavy attack. (Confirmed issue on Xbox One).
4) The glitched wings that prevent any actions while using Dragon Leap or its morphs. Sometimes the wings glitch out when using Dragon Leap and get permanently stuck on the character, making the character unable to perform any skills or actions. This usually results in death because the player is unable to attack. Sometimes drinking a potion, if one is available, may override the glitch. (Confirmed issue on Xbox One).
5) The "Summon a shade version of yourself" tooltip language for Nightblade's Summon Shade and Shadow Image morph. The language suggests that the character creates a shade version of themselves, but if a player is a Khajiit or Argonian, the shades are human. A simple update to the tooltip language could fix this minor issue. Just say something simple like, "summon a shade." Then the shade is its own entity.
If anyone else wants to add to this list, please list anything I haven't mentioned.
