Fire damage seems to be not in line with other damage types in the game.
[Alliance] Le-Shan@gabrieldourden : [Combat (Self)] Critical Hit! Kabal's Chosen deals 105236 (210472) Fire Damage to you with Fire.
This is a dot I got in the River District by touching for a moment a fire area (Alagondar's champion fire on the ground). I'm a level 80 character with 306k hit points and 80k defense and got killed in a few seconds with no way to escape.
Puppet (2 star hunt) in Barovia is doing similar stuff.
Not to mention hits like this:
[Combat (Self)] Critical Hit! Kabal's Chosen deals 250794 Fire Damage to you with Fire.
This went straight through my defense, by the way.
Non-fire attacks in the River district deal far less damage.
This has been happening for a long time and I think somebody should take a look at it as I believe it is not WAI.
