Not sure if this is intended, or if it's because I play on the original Xbox One. But, the visual effects on other players skills are mostly unseen. I can sometimes see some effects, and others none at all.
This is a huge concern in PvP as making sure you're reading your opponent's actions play a massive part. If I cannot tell what abilities are being used, I stand at an unimaginable disadvantage. I plan to upgrade my Xbox either way, but that doesn't mean that by using my current console I should be unable to compete.
