Can We Please have a Combat Log

Value add:
Player has direction on what killed them
By how much health
By what effect
By what type of damage
Player can make adjustment
Less whining on forums that no clue why one shot.
Player knows what direction to take with gear and build.

Cons:
Maybe generate whining from players about too much damage done
Might expose issues
Might expose some mobs actually are overtuned.
New flavor of player whining due to data provided. But at least that would be whing based on facts vs random. May even get feedback from the pro players that some things are just need balance/adj.
