What's the point of Physical and Magic Damage Types

[KageTokage]

You see that spell the enemy mage is casting?..

...... that's definitely physical damage.

And for the love of Hydaelyn, don't even start with "Just make it all one type of damage" to dumb it down...

That's not 100% consistent and there are instances where "casts" and "prepares" can deal physical or magical damage respectively.

I'm not sure why people are trying to defend obtuse damage tells in an environment where failing to mitigate properly can result in one-shots in harder content. DRK in particular has problems with this because Dark Mind is generally a really strong personal mitigation due to its short cooldown, but I see DRKs popping it on things like the E12 tankbusters that you could easily assume are magical damage if you haven't done the savage version where the vulnerability debuffs reveal the truth.

Another thing that needs distinction is darkness and gravity damage because most forms of mitigation in general don't work on those (E1S being the most prominent example of this as virtually all of the raidwides fall into the latter camp).
