Well, the combat log been a long time peeve of mine. With the recent champions killing me all the time, what I find most annoying isn't the arbitrary computer generated randomness, but the darn combat log.
I can't go back to see what the heck killed me, to learn from my mistakes, to improve, to change strategy.
Can we get a longer log? With better detail and descriptions? Can't even match the damage numbers flying in the screen with the log. It doesn't even log what type of damage killed me or how much damage it did. You have to watch the floaty numbers and guess what it was.
If there is slightly more benevolence, perhaps the log can be color coded to represent attack vs defense, to highlight mob name, highlight damage numbers... but I'm not holding my breath. Just fix the log to be accurate and informative first. We can do the parsing ourselves at least.
