The Mayhem berzerker engraving enables permanent burst mode. While running this build, there’s pretty much no reason to not be in Burst mode, which makes it annoying that entering non-combat zones or switching to certain areas (like guardian raids etc.) turns it off.
One thing is forgetting that you’ve not gone to Burst mode while fighting in a new area, which to me as a new berzerker happens often. Keeping the Burst mode on/off even cross-zones etc. would be great.
Other annoying thing is that after entering a city, the player keeps their 25% health, which now adds the almost-dead effects like the heart-beat and the red screen. This then lasts some time until you naturally heal or use a potion to get more health. These effects can last for a couple of minutes without a potion, which makes me feel extremely anxious
