Partly...PvE? Nope not at all, you can use whatever you want. PvP? This is where it affects other people, I absolutely hate playing Mayhem now as it’s just full of Hunters spamming Blade Barrage non stop with Shards. So because of Shards in Mayhem my enjoyment has gone down to zero. That’s the only time it has really bugged me, players can use OEM with Blue Rocks and Not Forgotten for all care as that doesn’t bother me one bit
